Visible-light harvesting 2D copper-cluster-based MOFs as efficient ROS generators for selective oxidation of amines

We have designed and synthesized an aesthetically appealing two-dimensional copper-cluster-based organic framework material named Cu-BPYC. This material exhibits superior charge separation and transfer efficiency, as well as reactive oxygen species (ROS) generation capability under visible-light irradiation. Through the synergistic mechanisms of photo-induced energy and charge transfer, it effectively promotes the oxidation of amines to imines. Additionally, Cu-BPYC demonstrates excellent structural stability and reusability in heterogeneous catalytic systems.
