Constructing a powerful photocatalytic system that can achieve the carbon dioxide (CO2 ) reduction half-reaction and water (H2 O) oxidation simultaneously is very challenging but meaningful task. Herein, porous material with crystalline topological network, named viCOF-bpy-Re, was rationally synthesized by incorporating rhenium complexes as reductive sites triazine ring structures oxidative via robust -C=C- bond linkages. The charge-separation ability of viCOF-bpy-Re promoted low polarized...
Covalent organic frameworks (COFs) with structural designability and tunability of photophysical properties enable them to be a promising class luminescent materials by incorporating well-designed fluorescent units directly into the periodic skeletons. The COFs are mainly affected features, which determine conjugation degree, charge delocalization ability, exciton dynamics COFs. To understand relationship between COF structures their properties, two same pyrene chromophore but different...

The vinylene-linked covalent organic frameworks (viCOFs) have been generally synthesized in the presence of homogeneous catalysts such as KOH or trifluoroacetic acid. However, highly ordered viCOFs cannot always be obtained due to uncommitted growth viCOF layers system with ubiquitous catalysts. Here, we propose a scalable protocol restrict along two-dimensional (2D) plane by introducing heterogeneous catalyst, polyoxometalates (POMs). With unique Brønsted alkalinity and catalytic surface,...

Two-dimensional (2D) covalent organic frameworks (COFs) with designable pore structures can be synthesized under the guidance of topology diagrams. Among five existing edge-transitive topological nets, kgd is considered a fine candidate for constructing COFs ultramicropores. However, all reported need use C6-symmetric monomers, which are limited in compound type and difficult to synthesize. Here, we first develop new approach construct 2D (clv-COFs) similar geometrical shape topology, named...
Abstract Fluorine‐containing 2D polymer (F‐2DP) film is a desired system to regulate the charge transport in organic electronics but rather rarely reports due limited fluorine‐containing building blocks and difficulties synthesis.
