Multicomponent one-pot construction of benzo[f]quinoline-linked covalent organic frameworks for H2O2 photosynthesis

The exploration of stable and functional linkages by multicomponent reactions to enrich the stability and diversity of covalent organic frameworks (COFs) and to broaden their potential applications is of fundamental significance to the development of COFs. Herein, we report the facile construction of a set of benzo[f]quinoline-linked COFs (B[f]QCOFs) via one-pot three-component [4 + 2] cyclic condensation of aldehydes and aromatic amines with easy-to-handle triethylamine as the vinyl source. These B[f]QCOFs possess high crystallinity, good physico-chemical stability as well as significant light absorption ability. More importantly, the obtained B[f]QCOF-1 exhibits a superior H2O2 production rate of 9025 μmol…
