Herein, a synthesis of a dual-functional cobalt covalent organic framework (CoCOF-SYNU-1) for visible-light-driven C-H annulation of amides with alkynes was reported. An at.-level cobalt center ensures the occurrence of powerful chelation with amides and subsequent precise C-H activation, while the photoactive covalent organic framework was responsible for absorbing visible light to accelerate the catalytic cycle. In the presence of CoCOF-SYNU-1, visible-light-driven regioselective [4 + 2] C-H annulation proceeded smoothly, delivering a wide range of isoquinolin-1(2H)-one derivatives I [R1 = n-Pr, n-Bu, Ph, etc.; R2 = H, n-Pr, trimethylsilyl, etc.; R3 = H, 6-Me, 8-I, etc.; Q = 8-quinolyl] with high efficiency. Significantly, due to the inherent heterogeneous nature and good stability of CoCOF-SYNU-1, the reaction exhibited excellent catalyst recyclability and practicability.
