Construction of Covalent Triazine Framework With D‐A <sub>1</sub> ‐A <sub>2</sub> Configuration via Post‐Modification for Photocatalytic Hydrogen Evolution
ABSTRACT A D‐A 1 ‐A 2 type covalent triazine framework (CTF) was prepared for the photocatalytic hydrogen evolution (HER). In the resulting CTF‐CZ‐Bpy 2+ , 9‐ethyl‐9 H ‐carbazole (CZ) group is used as the donor, triazine ring as the first acceptor, and cyclic diquat (Bpy 2+ ) moiety as the second acceptor. Both experimental and theoretical results show that the D‐A 1 ‐A 2 structure significantly enhances the efficiency of photogenerated charge separation and transfer. As a result, CTF‐CZ‐Bpy 2+ demonstrated outstanding photocatalytic HER activity with a yield rate of 31.1 mmol g −1 h −1 , which is 7.8 times higher than that of nonfunctionalized CTF‐CZ‐Bpy.
