Donor–Acceptor Fully Sp 2 ‐Carbon Conjugated Covalent Organic Frameworks for Photocatalytic H 2 O 2 Production
Qingdao Agricultural University · Beijing University of Chemical Technology
Abstract
Abstract Covalent organic frameworks (COFs) are promising for photocatalytic H₂O₂ generation. However, imine‐linked COFs often suffer from poor charge separation and low photocatalytic performance. Therefore, constructing sp 2 carbon‐linked COFs with extended π‐conjugation is very significant in boosting the photocatalytic properties, but their synthesis is challenging due to the low reversibility of C═C bond. Here, two vinylene‐linked COFs: BBT‐ACN COF‐1 and BBT‐ACN COF‐2 are designed. To investigate the effects of different structures on exciton binding energy ( E b ), the designed BBT‐ACN COF‐1 possesses a Donor–Acceptor (D–A) structure with the electron‐deficient benzobisthiazole (BBT) as acceptor and…
