• A quinoline-based covalent organic framework (N^N)- Q-COF was constructed with chemically stable networks and (N^N)-sites. Its coordination bond with Ir(C^N) 2 (N^N) units generated new entities with exciting photophysical properties; particularly, the incorporation of a coumarin ligand greatly elevated its properties to a higher level. The further anchoring of NiCl 2 produced structures merging both photoredox and organometallic catalysts, resulting in excellent photocatalytic activities in C-S and C-N cross-coupling synthesis. The organic integration of Ir(C^N) 2 (N^N), NiCl 2 , and COFs and the advantages of COF networks were responsible for this transcendent dual catalysis. The chemical stability of Q-COFs and the coordination anchoring of Ir(C^N) 2 (N^N) and NiCl 2 enabled its recycling and reuse with no reduction in catalytic performance. The incorporation of Ir(C^N) 2 (N^N)-NiCl 2 in quinoline-based (N^N)-covalent organic framework exhibits remarkable photocatalytic activities in cross-coupling synthesis.
