Photocatalytic reduction of carbon dioxide into useful feedstocks has attracted increasing attention. In this study, a fully conjugated COF material COF-TMT-A with the main structure containing an alkyne group and triazine part was synthesized using sp 2 -carbon–carbon double bond (C=C) linked COF as a research target. The prepared COF materials were characterized in detail by FT-IR, PXRD, and 13 C solid-state NMR. The introduction of an alkyne group not only enhanced the conjugated π-electron leaving domain but also optimized the electronic band structure and significantly improved the photocatalytic activity. The selectivity for the product HCOO was as high as 99%. A 10 h photocatalytic CO 2 reduction experiment was carried out, and COF-TMT-A showed a significantly higher HCOO − yield of about 43 μmol compared with COF-701 and the ligand. [ABSTRACT FROM AUTHOR]
