Three-dimensional molecular donors combined with polymeric acceptors for high performance fullerene-free organic photovoltaic devices

Liu, Shi-Yong,Jung, Jae Woong,Li, Chang-Zhi,Huang, Jiang,Zhang, Jianyuan,Chen, Hongzheng,Jen, Alex K.-Y.

, p. 22162 - 22169 (2015)

Non-fullerene acceptor based organic photovoltaic devices (OPVs) reported so far are inferior to those derived from fullerenes. This increases the speculation on whether donors need to be tailored for advancing non-fullerene OPVs. We explored herein two direct arylation-derived diketopyrrolopyrrole (DPP)-based three-dimensional (3D) donors that can deliver respectable power conversion efficiencies (PCEs) of 4.64% and 4.02% with polymeric acceptor N2200 blends, surpassing those obtained from PC71BM (3.56% and 3.22%, respectively). It is found that these 3D-shaped molecular donors can yield improved photo-to-current conversion and balanced charge transport when blending with the linear N2200 polymer. This finding suggests that engineering molecular geometry can be a promising approach for developing high-performance materials.

All-Carbon-Linked Continuous Three-Dimensional Porous Aromatic Framework Films with Nanometer-Precise Controllable Thickness

B?rjesson, Karl,Evans, Austin M.,Ratsch, Martin,Yang, Yizhou,Ye, Chen,Zhang, Airui

, p. 6548 - 6553 (2020)

Inherently porous materials that are chemically and structurally robust are challenging to construct. Conventionally, dynamic chemistry is thought to be needed for the formation of uniform porous organic frameworks, but dynamic bonds can limit the stability of these materials. For this reason, all-carbon-linked frameworks are expected to exhibit higher stability performance than more traditional porous frameworks. However, the limited reversibility of carbon-carbon bond-forming reactions has restricted the exploration of these materials. In particular, the challenges associated with producing uniform thin films of all-carbon-linked frameworks has inhibited the study of these materials in applications where well-defined films are required. Here, we synthesize continuous and homogeneous films of two different all-carbon-linked three-dimensional porous aromatic frameworks with nanometer-precision thickness (PAF-1 and BCMP-2). This was accomplished by kinetically promoting surface reactivity while suppressing homogeneous nucleation. Through connection of the PAF film to a gold substrate via a self-assembled monolayer and use of flow conditions to continually introduce monomers, smooth and continuous PAF films can be grown with controlled thickness. This strategy allows traditional transition metal mediated carbon-carbon cross-coupling reactions to form porous, organic thin films. We expect that the chemical principles uncovered in this study will enable the synthesis of a variety of chemically and structurally diverse carbon-carbon-linked frameworks as high-quality films, which are inaccessible by conventional methods.

Thiazolothiazole-linked porous organic polymers

, p. 15055 - 15058 (2014)

Thiazolothiazole-linked porous organic polymers have been synthesized from a facile catalyst-free condensation reaction between aldehydes and dithiooxamide under solvothermal conditions. The resultant porous frameworks exhibit a highly selective uptake of CO2 over N2 under ambient conditions. This journal is

Luminescent infinite coordination polymer materials from metal-terpyridine ligation

Eryazici, Ibrahim,Farha, Omar K.,Compton, Owen C.,Stern, Charlotte,Hupp, Joseph T.,Nguyen, Sonbinh T.

, p. 9189 - 9193 (2011)

A new class of infinite coordination polymers (CP) was synthesized using a tetrahedral tetrakis[4-(4′-phenyl-2,2′:6′,2′′- terpyridine)phenyl]methane ligand as an organic node to direct the three-dimensional growth of the network and MII (M = Zn, Fe, Ni, and Ru) ions as inorganic linkers, an approach that is the opposite of the metal-as-a-node strategy used in the construction of metal-organic frameworks (MOFs). The unusual rod-like morphology of the resulting microporous materials can be tuned via solvents and reaction conditions. The covalent entrapment of a [Ru(tpy)2]2+ moiety in the skeleton of the 3D-network enables the Ru-CP to exhibit room-temperature luminescence.

Synthesis and fine-tuning the pore properties of a thiophene based porous organic framework by post-oxidation treatment

Liu, Yanze,Zuo, Yiming,Li, Shuai,Li, Jiani,Li, Li,Liu, Caixia,Ashraf, Shumalia,Li, Pengfei,Wang, Bo

, p. 21953 - 21958 (2019)

Porous organic frameworks (POFs) are an important class of materials, which have attracted great interests in recent years. The post modification of porous organic frameworks provides an efficient way to fine tune the properties of POFs for specific applications. However, most of the post functionalization methods need harsh reaction conditions and specific reagents and lead to a notable pore width decrease, which hinder the pore accessibility. Herein, we designed and synthesized a thiophene based POF with high surface area and stability. A straightforward post-oxidation of thiophene based POFs by meta-chloroperbenzoic acid introduced sulfone groups as hydrogen bonding sites in the channel with a less effected pore width in a controllable manner. The hydrogen bond acceptor sulfone groups could promote the adsorption of ammonia and enhance the proton conductivity of phosphoric acid or imidazole infiltrated POFs. The proton conductivity of phosphoric acid doped oxidized thiophene based POFs is over 10-3 S cm-1 at 120 °C under anhydrous conditions, which could be a promising candidate for fuel cells.

Two-Photon Absorption Properties and Structures of BODIPY and Its Dyad, Triad and Tetrad

Yang, Jian,Rousselin, Yoann,Bucher, Léo,Desbois, Nicolas,Bolze, Frédéric,Xu, Hai-Jun,Gros, Claude P.

, p. 838 - 844 (2018)

A series consisting of a dyad, a triad and a tetrad containing either two, three and four BODIPY units, respectively, has been synthesized and fully characterized and compared to two mono-BODIPY analogs (used as references). The one- and two-photon photophysical properties have been measured and the X-ray structures of four of the BODIPY derivatives have been determined. In the 700–900 nm range, the two-photon absorption (TPA) cross sections range from 30 GM to 160 GM for these compounds.

Gold nanoparticles confined in imidazolium-based porous organic polymers to assemble a microfluidic reactor: Controllable growth and enhanced catalytic activity

Fang, Haobin,Sun, Shujian,Liao, Peisen,Hu, Ya,Zhang, Jianyong

, p. 2115 - 2121 (2018)

A synthetic strategy is developed to grow Au nanoparticles supported by imidazolium-based porous organic polymers (Au/IM-POPs) along the inner surface of a fused-silica microfluidic capillary. The thickness of the hybrid Au/IM-POP material layers can be tuned by changing the precursor concentration. A variety of imidazolium-based porous organic polymers are developed from tetrakis[4-(1-imidazolyl)phenyl]methane and bromo-functionalized linker molecules and fully characterized, which may be used to support Au nanoparticles. Additionally the IM-POPs and Au/IM-POPs show porosity and the ability to take up guest molecules. The capillary coated with Au/IM-POPs is further assembled to obtain a catalytic microfluidic reactor. The catalytic activity of Au nanoparticles supported by the porous imidazolium polymer is probed by using the reduction of nitrobenzene derivatives flowing through the microfluidic reactor. The catalytic microfluidic reactor demonstrates significantly enhanced turnover frequency magnitudes in comparison with the corresponding reactions under batch conditions.

Synthesis of TEMPO radical decorated hollow porous aromatic frameworks for selective oxidation of alcohols

Shen, Yan-Ming,Xue, Yun,Yan, Mi,Mao, Hui-Ling,Cheng, Hu,Chen, Zhuo,Sui, Zhi-Wei,Zhu, Shao-Bin,Yu, Xiu-Jun,Zhuang, Jin-Liang

, p. 907 - 910 (2021)

A bottom-up approach was developed to prepare TEMPO radical decorated hollow aromatic frameworks (HPAF-TEMPO) by using TEMPO radical functionalized monomers and SiO2nanospheres as templates. The accessible inner layer, high density of TEMPO sites, and hybrid micro-/mesopores of the HPAF-TEMPO enable the aerobic oxidation of a broad range of alcohols with high efficiency and excellent selectivity.

Symmetry-guided synthesis of highly porous metal-organic frameworks with fluorite topology

Zhang, Muwei,Chen, Ying-Pin,Bosch, Mathieu,Gentle III, Thomas,Wang, Kecheng,Feng, Dawei,Wang, Zhiyong U.,Zhou, Hong-Cai

, p. 815 - 818 (2014)

Two stable, non-interpenetrated MOFs, PCN-521 and PCN-523, were synthesized by a symmetry-guided strategy. Augmentation of the 4-connected nodes in the fluorite structure with a rigid tetrahedral ligand and substitution of the 8-connected nodes by the Zr/Hf clusters yielded MOFs with large octahedral interstitial cavities. They are the first examples of Zr/Hf MOFs with tetrahedral linkers. PCN-521 has the largest BET surface area (3411 m 2 g-1), pore size (20.5×20.5×37.4 A?) and void volume (78.5%) of MOFs formed from tetrahedral ligands. This work not only demonstrates a successful implementation of rational design of MOFs with desired topology, but also provides a systematic way of constructing non-interpenetrated MOFs with high porosity. Meet me at the symmetry gates: Using a symmetry-guided design strategy, two stable, non-interpenetrated MOFs, were synthesized by augmenting the fluorite topology with tetrahedral linkers, thus expanding the cavity size (see scheme) and giving the largest pore size of any MOF with tetrahedral ligands.

Anhydrous proton conduction in porous organic networks

Klumpen,Winterstein,Papastavrou,Senker

, p. 21542 - 21549 (2018)

Solid electrolyte separators within fuel cells enable efficient charge transport and prevent a mass bypass between the two half cells. Hydrated systems, like Nafion, reach unprecedented proton conductivities at ambient temperatures, but the demanding humidity management prevents their use beyond 80 °C, hence limiting the efficiency of current polymer-based systems. As such, water free and chemically inert, solid materials with excellent conductivities between 100 °C and 200 °C, are of high interest. A promising approach is the incorporation of heavier amphoteric molecules into micro- and mesoporous frameworks. Stronger host-guest interactions allow for higher temperatures, while still maintaining sufficient mobility and efficient transport pathways. Here, we present a systematic study investigating the influence of porosity, framework topology and dimensionality as well as framework functionality and charge carrier uptake on the proton conductivity for six porous organic networks (PONs) loaded with imidazole via gas phase adsorption. The resulting materials were thoroughly characterized by multinuclear NMR and IR spectroscopy and physisorption as well as powder X-ray diffraction and DSC experiments, revealing homogeneous distribution of the amphoteric guests within the pore structure. Electrochemical impedance spectroscopy up to 130 °C revealed remarkable conductivities of up to 10?3 S cm?1 under anhydrous conditions. We found 3D networks to favour high imidazole loading leading to high proton conductivities based on the Grotthuss mechanism. In contrast, 2D networks showed a lower guest molecule uptake and thus lower proton conductivities, which were governed by vehicle transport. Additional acid/base functionalities within the frameworks seem to have a negative effect on the proton conduction.

Harms, Sven,K?ferstein, Roberto,G?rls, Helmar,Robl, Christian

, p. 912 - 918 (2019)

Colorless single crystals of Cd2[μ8-MTB]·3H2O·DMF (1) were prepared in DMF/H2O solution [1: space group C2/c (no. 15) with a = 1821.30(6), b = 2175.08(6), c = 1269.87(4) pm, β = 129.684(1)°]. The connection between the methane-p-benzoate tetraanions (MTB4–) and the Cd2+ cations leads to a three-dimensional framework with channels extending along [110] and [110] with openings of 670 pm × 360 pm. The channel-like voids accommodate water molecules and N,N-dimethylformamide (DMF) molecules not bound to Cd2+. Colorless single crystals of [Cd4(2,2′-bipy)4(μ7-MTB)2]·7DMF (2) were prepared in DMF in the presence of 2,2′-bipyridine [2: space group P1 (no. 2) with a = 1224.84(4), b = 1418.85(5), c = 2033.49(4) pm, α = 85.831(2)°, β = 88.351(2)°, γ = 68.261(1)°]. The coordination of MTB4– to Cd2+ results in infinite layers parallel to (001). The layers, not connected by any hydrogen bonds, contain small openings of about 320 pm × 340 pm.

Introduction of π-complexation into porous aromatic framework for highly selective adsorption of ethylene over ethane

Li, Baiyan,Zhang, Yiming,Krishna, Rajamani,Yao, Kexin,Han, Yu,Wu, Zili,Ma, Dingxuan,Shi, Zhan,Pham, Tony,Space, Brian,Liu, Jian,Thallapally, Praveen K.,Liu, Jun,Chrzanowski, Matthew,Ma, Shengqian

, p. 8654 - 8660 (2014)

In this work, we demonstrate for the first time the introduction of π-complexation into a porous aromatic framework (PAF), affording significant increase in ethylene uptake capacity, as illustrated in the context of Ag(I) ion functionalized PAF-1, PAF-1-SO3Ag. IAST calculations using single-component-isotherm data and an equimolar ethylene/ethane ratio at 296 K reveal that PAF-1-SO3Ag shows exceptionally high ethylene/ethane adsorption selectivity (Sads: 27 to 125), far surpassing benchmark zeolite and any other MOF reported in literature. The formation of π-complexation between ethylene molecules and Ag(I) ions in PAF-1-SO 3Ag has been evidenced by the high isosteric heats of adsorption of C2H4 and also proved by in situ IR spectroscopy studies. Transient breakthrough experiments, supported by simulations, indicate the feasibility of PAF-1-SO3Ag for producing 99.95%+ pure C 2H4 in a Pressure Swing Adsorption operation. Our work herein thus suggests a new perspective to functionalizing PAFs and other types of advanced porous materials for highly selective adsorption of ethylene over ethane.

Rigid Multidimensional Alkoxyamines: A Versatile Building Block Library

Matt, Yannick,Wessely, Isabelle,Gramespacher, Lisa,Tsotsalas, Manuel,Br?se, Stefan

, p. 239 - 245 (2020/12/17)

Since the discovery of the “living” free-radical polymerization, alkoxyamines were widely used in nitroxide-mediated polymerization (NMP). Most of the known alkoxyamines bear just one functionality with only a few exceptions bearing two or more alkoxyamine units. Herein, we present a library of novel multidimensional alkoxyamines based on commercially available, rigid, aromatic core structures. A versatile approach allows the introduction of different sidechains which have an impact on the steric hindrance and dissociation behavior of the alkoxyamines. The reaction to the alkoxyamines was optimized by implementing a mild and reliable procedure to give all target compounds in high yields. Utilization of biphenyl, p-terphenyl, 1,3,5-triphenylbenzene, tetraphenylethylene, and tetraphenyl-methane results in linear, trigonal, square planar, and tetrahedral shaped alkoxyamines. These building blocks are useful initiators for multifold NMP leading to star-shaped polymers or as a linker for the nitroxide exchange reaction (NER), to obtain dynamic frameworks with a tunable crosslinking degree and self-healing abilities.

Unusual Metal-Organic Framework Topology and Radiation Resistance through Neptunyl Coordination Chemistry

Burns, Peter C.,Chen, Zhijie,Fairley, Melissa,Farha, Omar K.,Gilson, Sara E.,Hanna, Sylvia L.,Julien, Patrick,Laverne, Jay A.,Szymanowski, Jennifer E. S.

supporting information, p. 17354 - 17359 (2021/11/04)

A Np(V) neptunyl metal-organic framework (MOF) with rod-shaped secondary building units was synthesized, characterized, and irradiated with γrays. Single-crystal X-ray diffraction data revealed an anionic framework containing infinite helical chains of actinyl-actinyl interaction (AAI)-connected neptunyl ions linked together through tetratopic tetrahedral organic ligands (NSM). NSM exhibits an unprecedented net, demonstrating that AAIs may be exploited to give new MOFs and new topologies. To probe its radiation stability, we undertook the first irradiation study of a transuranic MOF and its organic linker building block using high doses of γrays. Diffraction and spectroscopic data demonstrated that the radiation resistance of NSM is greater than that of its linker building block alone. Approximately 6 MGy of irradiation begins to induce notable changes in the long- and short-range order of the framework, whereas 3 MGy of irradiation induces total X-ray amorphization and changes in the local vibrational bands of the linker building block.
