Supramolecular Organic Photocatalyst Containing a Cubanelike Water Cluster and Donor–Acceptor Stacks: Hydrogen Evolution and Dye Degradation under Visible Light

Supramolecular organic photocatalysts are scarcely explored for the generation of sustainable energy as well as for environmental remediationpurposes. An organic photocatalyst, containing a cubanelike water clusterand donor–acceptor stacks, was efficiently developed through a supramolecular approach. The material exhibited remarkable photocatalytic hydrogen generation, in the absence of any cocatalyst, with excellent stability and recyclability. The photoactivity was further assessed through time-resolved photoluminescence and electrochemical impedance spectroscopy. The material also exhibited highly efficient sunlight-driven photocatalytic activity through the degradation of harmful organic dye methylene blue.
