Anchorage of Ru(N^N)3 in (N^N)‐Covalent Organic Framework for Enhanced Photocatalytic Sulfide and Amine Oxidation

Abstract An imine‐linked covalent organic framework incorporating N^N coordination units was successfully synthesized, resulting in the formation of the Ru(N^N) 3 ‐COF photocatalyst through the anchoring of [Ru(bpy)₂] 2 ⁺ onto the framework. Comprehensive characterization using various analytical techniques confirmed the structure and integrity of Ru(N^N) 3 ‐COF. The integration of the Ru(N^N) 3 unit significantly improved the light‐harvesting capabilities and charge separation efficiencies of the COF, leading to remarkable photocatalytic performance in the oxidation reactions of sulfides and amines. Additionally, this heterogeneous catalyst exhibited outstanding chemical stability and recyclability, highlighting its potential for practical applications.
