Homologous heteropolyaromatic covalent organic frameworks for enhancing photocatalytic hydrogen peroxide production and aerobic oxidation.

ABSTRACT: The development of robust catalysts that can work under harsh conditions bring promise but a challenge for photocatalytic hydrogen peroxide production. Here, we report the design of thiazole-based homologous heteropolyaromatic COFs (TTT-COF) via post-cyclization reaction for photocatalytic H₂O₂ production and aerobic oxidation of C(sp³)-H bonds. Our studies demonstrate that the elemental S heteroatom enables modified COF materials with high chemical stability, continuous π-conjugation, efficient electron and energy transfer, and an enhanced donor-acceptor (D-A) structure and charge separation, thus boosting their intrinsic photocatalytic activities and stability. Consequently, TTT-COF achieves a photosynthetic H₂O₂ production rate of 2
