Donor–acceptor covalent organic framework (COF) materials have proven to be an optimal choice for heterogeneous photocatalysis due their capacity effective charge separation and harvesting of visible light. The poor chemical photostability imine-linked D–A COFs restrict potential broader applications. So, researchers are focused on developing with enhanced photocatalytic activity. In this study, we also emphasize the pivotal role molecular engineering overcome these challenges. Herein, a carbazole-based highly crystalline CzDA-TAPT COF was developed. Not only does incorporation alkyl group-substituted carbazole provide excellent donor ability, but butyl groups in pore skeleton guide attachment successive layers different AB stackings, significantly amplifying efficiency by providing more active sites reaction. Compared previously reported photoactive benzothiadiazole-based COFs, innovative material exhibits superior heightened photostability, resulting notable advancement aerobic oxidation aryl boronic acids phenols.

Lead halide hybrids have emerged as highly efficient photocatalysts, yet their application in photocatalytic organic synthesis remains limited, largely due to instability upon polar organics. Herein, we developed an isoreticular synthetic strategy functionalize lead chloride-based MOFs with azonbenzene units, a benchmark photoresponsive moiety. The three consist of isostructural 1D [PbCl]+ chains SBUs and biphenyl/azobenzene dicarboxylates struts. Compared the parent biphenyl-MOF, azobenzene-functionalized demonstrate broad wavelength coverage up 620 nm. Their photoinduced ligand-to-metal charge transfer affords enhanced electron–hole separation for long-lived free carriers. Among them, 4,4′-azobenzene-functionalized MOF exhibits most aerobic oxidation both C(sp3)-H photooxidation benzylamine coupling. Meanwhile, these coordination assembled exhibit high stability wide pH range compounds. This work showcases rational modify at molecular level while preserving lattice topology.

Developing effective photocatalysts for the oxidation reaction is of great significance in chemical synthesis but still challenging. Herein, linking photochromic triphenylamine with pyrene units by situ formed robust imidazole moieties, a covalent organic framework (COF), PyNTB-COF, containing rare donor-acceptor-π-acceptor-donor (D-A-π-A-D) fragment, was successfully synthesized photocatalytic aerobic oxidation. Structure characterizations confirm its crystalline framework, high porosity, and good stability. Property studies reveal photoelectric semiconductor feature photoresponsive charge separation migration activity derived from D-A-π-A-D fragments, proven experimental results theoretical calculations. Photocatalytic experiments not only display highly triggering generation ·O2- under visible light irradiation also exhibit efficiency oxidations toluene amidation aldehydes. This work demonstrates that integration into materials to construct π-conjugated D-A moieties could enhance efficiency, achieving promising
