Covalent organic frameworks (COFs) have attracted growing interests as new material platform for a range of applications. In this study, triazine-carbazole-based covalent framework (COF-TCZ) was designed highly porous with conjugated donor-acceptor networks, and feasibly synthesized by the Schiff condensation 4,4',4''-(1,3,5-triazine-2,4,6-triyl)tr ianiline (TAPB) 9-(4-formylphenyl)-9H-carbazole-3,6-dicarbaldehyde (CZTA) under solvothermal condition. Considering effect linkage, imine-linked COF-TCZ further oxidized to obtain an amide-linked (COF-TCZ-O). The as-synthesized COFs show high crystallinity, good thermal chemical stability, excellent photoactive properties. Two π-conjugated tunable linkages are beneficial light-harvesting capacity charge separation efficiency, which empolyed photocatalysts oxidation reaction N-aryltetrahydroisoquinoline. catalyst systems exhibit outstanding photocatalytic performance conversion, photostability recyclability. Photoelectrochemical tests were employed examine behavior photogenerated carriers in photo-illumination system. control experiments provide insights into nature photocatalysis. addition, current research also provided valuable approach developing photofunctional meet challenge achieving great potential materials conversion.
