- Tailored Band Gaps in Sulfur- and Nitrogen-Containing Porous Donor–Acceptor Polymers
-
Donor–acceptor dyads hold the key to tuning of electrochemical properties and enhanced mobility of charge carriers, yet their incorporation into a heterogeneous polymer network proves difficulty owing to the fundamentally different chemistry of the donor and acceptor subunits. A family of sulfur- and nitrogen-containing porous polymers (SNPs) are obtained via Sonogashira–Hagihara cross-coupling and combine electron-withdrawing triazine (C3N3) and electron-donating, sulfur-containing linkers. Choice of building blocks and synthetic conditions determines the optical band gap (from 1.67 to 2.58 eV) and nanoscale ordering of these microporous materials with BET surface areas of up to 545 m2 g?1 and CO2 capacities up to 1.56 mmol g?1. Our results highlight the advantages of the modular design of SNPs, and one of the highest photocatalytic hydrogen evolution rates for a cross-linked polymer without Pt co-catalyst is attained (194 μmol h?1 g?1).

- Fluorescent Sulphur- and Nitrogen-Containing Porous Polymers with Tuneable Donor–Acceptor Domains for Light-Driven Hydrogen Evolution
-
Light-driven water splitting is a potential source of abundant, clean energy, yet efficient charge-separation and size and position of the bandgap in heterogeneous photocatalysts are challenging to predict and design. Synthetic attempts to tune the bandgap of polymer photocatalysts classically rely on variations of the sizes of their π-conjugated domains. However, only donor–acceptor dyads hold the key to prevent undesired electron-hole recombination within the catalyst via efficient charge separation. Building on our previous success in incorporating electron-donating, sulphur-containing linkers and electron-withdrawing, triazine (C3N3) units into porous polymers, we report the synthesis of six visible-light-active, triazine-based polymers with a high heteroatom-content of S and N that photocatalytically generate H2 from water: up to 915 μmol h?1 g?1 with Pt co-catalyst, and—as one of the highest to-date reported values ?200 μmol h?1 g?1 without. The highly modular Sonogashira–Hagihara cross-coupling reaction we employ, enables a systematic study of mixed (S, N, C) and (N, C)-only polymer systems. Our results highlight that photocatalytic water-splitting does not only require an ideal optical bandgap of ≈2.2 eV, but that the choice of donor–acceptor motifs profoundly impacts charge-transfer and catalytic activity.

- Amine-Linked Covalent Organic Frameworks as a Platform for Postsynthetic Structure Interconversion and Pore-Wall Modification
-
Covalent organic frameworks have emerged as a powerful synthetic platform for installing and interconverting dedicated molecular functions on a crystalline polymeric backbone with atomic precision. Here, we present a novel strategy to directly access amine-linked covalent organic frameworks, which serve as a scaffold enabling pore-wall modification and linkage-interconversion by new synthetic methods based on Leuckart-Wallach reduction with formic acid and ammonium formate. Frameworks connected entirely by secondary amine linkages, mixed amine/imine bonds, and partially formylated amine linkages are obtained in a single step from imine-linked frameworks or directly from corresponding linkers in a one-pot crystallization-reduction approach. The new, 2D amine-linked covalent organic frameworks, rPI-3-COF, rTTI-COF, and rPy1P-COF, are obtained with high crystallinity and large surface areas. Secondary amines, installed as reactive sites on the pore wall, enable further postsynthetic functionalization to access tailored covalent organic frameworks, with increased hydrolytic stability, as potential heterogeneous catalysts.

- (E)-1,2-Diphenylethene-based conjugated nanoporous polymers for a superior adsorptive removal of dyes from water
-
Conjugated microporous polymers (CMPs) as prospective adsorbents for organic pollutant treatments are extremely appealing for both basic and applied kinds of research due to their simplicity, high performance, low cost, and processing under ambient conditions. However, the development of CMPs having excellent pollutant adsorption behaviour is still challenging. Herein, we described the targeted synthesis of a series of (E)-1,2-diphenylethene-based CMPs - BIPE-BIPE, BIPE-Py, and BIPE-TPT CMPs - via [4 + 4] and [4 + 3] Suzuki-Miyaura polymerizations of the novel (E)-1,2-bis(3,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethene (BITPE-4Bpin) with 1,2-bis(3,5-dibromophenyl)ethene (BIPE-4Br), 1,3,6,8-tetrabromopyrene (Py-4Br), and 2,4,6-tris(4-bromophenyl)-1,3,5-triazine (TPT-3Br), respectively. The porosities, chemical structures, and morphologies of the three CMPs were studied. The synthesized CMPs displayed high BET surface areas (up to 1400 m2 g-1) and outstanding thermal stabilities (up to a Td10 of 604 °C and char yield of 81 wt%). In addition, the as-prepared CMPs showed an extraordinarily high adsorption capacity for the organic dye rhodamine B (RhB) from water; the maximum adsorption capacity for RhB was 1027 mg g-1. Interestingly, our CMPs exhibited good recyclability and quickly attained 99.6% of their maximal adsorption capacity within 3 min. Our CMPs with the excellent adsorption behaviour could be good materials for water treatment and purification applications.

- Kinetically Controlled Reticular Assembly of a Chemically Stable Mesoporous Ni(II)-Pyrazolate Metal-Organic Framework
-
The application scope of metal-organic frameworks (MOFs) is severely restricted by their weak chemical stability and limited pore size. A robust MOF with large mesopores is highly desired, yet poses a great synthetic challenge. Herein, two chemically stable Ni(II)-pyrazolate MOFs, BUT-32 and -33, were constructed from a conformation-matched elongated pyrazolate ligand through the isoreticular expansion. The two MOFs share the same sodalite-type net, but have different pore sizes due to the network interpenetration in BUT-32. Controlled syntheses of the two MOFs have been achieved through precisely tuning reaction conditions, where the microporous BUT-32 was demonstrated to be a thermodynamically stable product while the mesoporous BUT-33 is kinetically favored. To date, BUT-32 represents the first example of Ni4-pyrazolate MOF whose structure was unambiguously determined by single-crystal X-ray diffraction. Interestingly, the kinetic product BUT-33 integrates 2.6 nm large mesopores with accessible Ni(II) active sites and remarkable chemical stability even in 4 M NaOH aqueous solution and 1 M Grignard reagent. This MOF thus demonstrated an excellent catalytic performance in carbon-carbon coupling reactions, superior to other Ni(II)-MOFs including BUT-32. These findings highlight the importance of kinetic control in the reticular synthesis of mesoporous MOFs, as well as their superiority in heterogeneous catalysis.

- Synthesis and photophysical properties of fluorescent dyes based on triphenylamine, diphenylamine, diphenyl sulfone or triphenyltriazine derivatives containing an acetylene linkage group
-
In this study, ten fluorescent dyes were prepared based on three different kinds of central moiety, such as triphenylamine, diphenylsulfone or triphenyltriazine, which was coupled to either carbazole or naphthalimidinyl group via an acetylene linkage group. N-n-Butyl-carbazole, N-phenyl-carbazole or N-n-butyl-naphthalimide was coupled to the individual central moiety of triphenylamine, diphenyl sulfone, 2,4,6-triphenyl-1,3,5-trazine or diphenylamine using a Sonogashira coupling reaction in the final step. All dyes were confirmed their chemical structure by 1H NMR, GC-Mass and elemental analyses. The absorption properties and thermal stabilities of the fluorescent dyes were examined. Density Functional Theory (DFT) and Time-Dependent DFT calculations were carried out, in addition to geometry simulation, by using the Gaussian 09 program. In terms of fluorescence properties in this series, two dyes based on diphenyl sulfonyl and three dyes based on triphenylamine substituted by 1–3 of N-n-butyl-carbazole exhibited a blue emission, whereas three dyes based on triphenylamine substituted by 1–3 of N-n-butyl-naphthalimide were observed by a red emitter which can be attributable to both effects the bathochromic shifts in absorption maxima and larger Stokes shifts. In case of corresponding 2,4,6-triphenyl-1,3,5-trazine central moiety coupled to a carbazole ring, a green fluorescence was emitted. Results revealed that the fluorescence of the dyes is affected by the electron-donating strength of the acetylene linkages involved in the π-conjugation systems of the dyes.

- Strategic design of triphenylamine- and triphenyltriazine-based two-dimensional covalent organic frameworks for CO2 uptake and energy storage
-
Hexagonally ordered covalent organic frameworks (COFs) are interesting new crystalline porous materials that have massive potential for application in gas storage. Herein, we report the synthesis of two series of two-dimensional hexagonally ordered COFs - TPA-COFs and TPT-COFs - through one-pot polycondensations of tris(4-aminophenyl)amine (TPA-3NH2) and 2,4,6-tris(4-aminophenyl)triazine (TPT-3NH2), respectively, with triarylaldehydes featuring different degrees of planarity, symmetry, and nitrogen content. All the synthesized COFs exhibited high crystallinity, large BET surface areas (up to 1747 m2 g-1), excellent thermal stability, and pore size distributions from 1.80 to 2.55 nm. The symmetry and planarity of the monomers strongly affected the degrees of crystallinity and the BET surface areas of the resultant COFs. In addition, these COFs displayed excellent CO2 uptake efficiencies of up to 65.65 and 92.38 mg g-1 at 298 and 273 K, respectively. The incorporation of the more planar and higher-nitrogen-content triaryltriazine unit into the backbones of the TPA-COFs and TPT-COFs enhanced the interactions with CO2, leading to higher CO2 uptakes. Moreover, the synthesized COFs exhibited electrochemical properties because of their conjugated structures containing redox-active triphenylamine groups. This study exposes the importance of considering the symmetry and planarity of the monomers when designing highly crystalline COFs; indeed, the structures of COFs can be tailored to vary their functionalities for specific applications.

-
Pi-conjugated organic molecules featuring the donor–bridge–acceptor (D–π–A) structure have been widely used in semiconducting materials owing to their rigid structure, good thermal stability, excellent charge transfer, and high emission efficiency. To investigate the effect of the D–π–A molecular structure on the photophysical properties, in this contribution, three star-shaped D–π–A isomers based on the 2,4,6-triphenyl-1,3,5-triazine, spirofluorene, and triphenylamine moieties, that is, p-TFTPA, mp-TFTPA, and m-TFTPA, were synthesized by elaborately engineering the interconnecting position in the building-block units. The optophysical properties of these compounds were systematically explored by experiments and theory calculations. Definitively, changing the interconnecting position in these molecules played a significant role in the degree of π conjugation, which resulted in tunable emission colors from deep blue to green. Moreover, these isomers were employed as emissive dopants in organic light-emitting diodes. The highest external quantum efficiency of 2.3 % and current efficiency of 6.2 cd A?1 were achieved by using the p-TFTPA based device. This research demonstrates a feasible way to realize blue emitters by engineering D–π–A conjugation.

- Oxidation of Aromatic Compounds. V. Oxidation of Substituted Benzonitriles and 2,4,6-Triaryl-1,3,5-Triazines in System HSO3F-PbO2
-
Low-temperature oxidation of substituted benzonitriles by the system HSO3F-PbO2 proceeds with intermediate formation of cation-radicals and leads to substitution of hydrogen atoms of the methyl group or benzene ring. This reaction provides a route for preparation of chloromethylsubstituted benzonitriles, diarylmethanes, diaryls, arylfluorosulfonates and substituted benzamides with cyano groups. In the case of methyl derivatives of 2,4,6-triphenyl-1,3,5-triazine substitution of the first and then the second hydrogen atom of the same methyl group transforms it into hydroxy or chloromethyl group, or into the aldehyde function.
