Abstract
A benzodifuran-based donor-acceptor covalent organic framework was synthesized and employed for efficient simulated sunlight-driven photocatalytic hydrogen evolution from water, which exhibited a superior and steady hydrogen evolution rate of 1390 μmol g-1 h-1 and an outstanding apparent quantum yield (AQY) of 7.8% was obtained at 420 nm.
