Tetrahedral rigid core antenna chromophores bearing bay-substituted perylenediimides

Two new representative methane- and adamantane-centered 'antenna' tetramers bearing bay-substituted π-conjugated phenylethynyl-perylenediimides (PDICCPh) as chromophoric subunits, tetrakis-[1-(4-ethynylphenyl)-N,N′-bis(1-hexylheptyl)-perylene-3,4:9,10-tetracarboxylic diimide]-methane (1) and tetrakis-1,3,5,7-[1-(4-ethynylphenyl)-N,N′-bis(1-hexylheptyl)-perylene-3,4:9,10-tetracarboxylic diimide]-adamantane (2), have been synthesized and their structural aspects have been thoroughly investigated by NMR spectroscopy. These PDI tetramers (1 and 2) represent the first successful example of incorporating the bay-substituted phenylethynyl-perylenediimides into the large rigid core tetrahedral frameworks. In these PDI tetramers, dynamic NMR experiments revealed the existence of perylene-centered conformational dynamic equilibrium (ΔG≠=15-17 kcal/mol), the primary cause of the observed spectral broadening in conventional 1H NMR spectra (295 K). In addition, PDI tetramers 1 and 2 were found to possess exceptional (photo)chemical stability, and their corresponding photophysical properties (εmax～180,000; τFL=6.9 ns; ΦFL～60%) make them viable candidates for various photonic applications and are in good agreement with other related multichromophoric PDI-based systems.

Conjugated microporous polymer networks with adjustable microstructures for high CO2 uptake capacity and selectivity

A series of phenylene-based conjugated microporous polymers (CMPs) of the A6 + Mx (x = 2, 3, 4, 6) type were synthesized. By tuning the monomer length and geometry, the BET surface area of CMPs can be tuned from 571 to 1115 m2/

Synthesis and optical properties of σ-π Conjugated organic-inorganic hybrid gels

Organic-inorganic hybrid gels containing Si-vinylene units have been synthesized by a hydrosilylation reaction of tri- or tetra-ethynyl aryl compounds, 1,3,5-triethynylbenzene (TEB), 3,3,5,5-tetraethynylbiphenyl (TEBP), or tetrakis(4-ethynylphenyl)methane

A Triazole-Containing Metal-Organic Framework as a Highly Effective and Substrate Size-Dependent Catalyst for CO2 Conversion

A highly porous metal-organic framework (MOF) incorporating both exposed metal sites and nitrogen-rich triazole groups was successfully constructed via solvothermal assembly of a clicked octcarboxylate ligand and Cu(II) ions, which presents a high affinit

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

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.

Microwave-assisted unprotected Sonogashira reaction in water for the synthesis of polysubstituted aromatic acetylene compounds

A microwave-assisted, efficient and rapid Sonogashira reaction was developed for the synthesis of polysubstituted aromatic alkynes. The reaction was made environmentally friendly and easy to perform by replacing the traditional amine solvents with water.

Diamondoid architectures from halogen-bonded halides

The reactions between a tetrahedrally-shaped tecton, tetrakis(4-(iodoethynyl)phenyl)methane, and tetraphenylphosphonium halides readily afford interpenetrated and densely packed diamondoid architectures sustained by C-I?X- (X- = chloride, bromide, iodide) interactions. In all these halogen-bonded networks, the halide anions act as four-connecting nodes, while the tetraphenylphosphonium cations provide essential templating information and structural support.

Tetrahedral Tetrakis(p-ethynylphenyl) Group IV Compounds in Microporous Polymers: Effect of Tetrel on Porosity

Three Sonogashira–Hagihara polymerization protocols were applied for the synthesis of conjugated microporous polymers (CMPs) by using group IV tetra(p-ethynylphenyl) monomers with 1,4-diiodobenzene or 1,4-dibromobenzene. The optical properties and surface areas of the CMPs were compared and related to the preparation conditions and the geometry of the tetrahedral building block as obtained after X-ray analysis. In each series, surface areas decreased—independently from the chosen parameters of catalyst, base, and solvent—from carbon-centered CMPs (1595 m2 g?1) to silicon-, germanium-, and tin-centered (649 m2 g?1) networks.

Preparation of a bispyridine based porous organic polymer as a new platform for Cu(ii) catalyst and its use in heterogeneous olefin epoxidation

A new type of bispyridine (bpy) incorporated POP was prepared via a cobalt-catalyzed acetylene trimerization. Subsequent immobilization of CuCl2 gave POP-Cu(ii). This new heterogeneous catalyst displayed outstanding olefin oxidation activity compared to its homogeneous analogue, suggesting that the degradation of the homogeneous catalyst was successfully inhibited by site isolation.

Fluorinated microporous organic polymers: Design and applications in CO2adsorption and conversion

Fluorinated microporous organic polymers (F-MOPs) were designed, showing twice higher CO2adsorption capacity than corresponding non-fluorous MOPs. The incorporation of phenanthroline moieties into F-MOPs afforded them the ability to coordinate with Ag(I), and the resultant F-MOP-Ag(I) displayed high efficiency for the reaction of CO2with propargyl alcohols to form a-alkylidene cyclic carbonates at 25°C.
