Abstract

Ir(ĈN)₂(X̂N) derivatives showed remarkable photochemical properties, making them highly adaptable in the field of photocatalysis. By integration of [Ir(ppy)₂]⁺ units into the quinoline-linked covalent organic frameworks Q-COF containing (N̂N) coordination sites, a wider spectral response range is achieved, leading to the development of unique entities with fascinating photophysical characteristics. The addition of Pt⁰ further enhances the performance of [Ir(ppy)₂(N̂N)+Pt]@Q-COF for photocatalytic hydrogen evolution reaction, with the in situ utilization of photogenerated H₂ enabling efficient nitro reduction.
