The intrinsic structural advantages and tunability of covalent organic frameworks (COFs) have made them promising photocatalysts for various photocatalytic reactions. However, it remains a great challenge to systematically tune the linker lengths build linker-length-dependent structure-performance relationship COFs-based photocatalysts. Herein, five isoreticular COFs with sql underlying nets been successfully synthesized using benzothiadiazole-based ditopic aldehydes varied 1,3,6,8-tetrakis(4-aminophenyl)pyrene as building units. obtained exhibit significantly different activities toward aerobic oxidation. Remarkably, COF-containing vinyl group, HIAM-0020, exhibited best performance near-unity conversion selectivity oxidative benzylamine coupling within 2 h. experimental theoretical investigations indicate that HIAM-0020 exhibits faster charge separation ability lower migration resistance compared other four COFs. This work represents guidance rational design synthesis COF-based achieve efficient transformation.
