Supramolecular organic photocatalysts are scarcely explored for the generation of sustainable energy as well as for environmental remediation purposes. An organic photocatalyst, containing a cubanelike water cluster and 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.
超分子有机光催化剂在可持续能源的产生以及环境修复方面的应用研究甚少。本文通过超分子方法设计了一种含有立方烷状水簇和给体-受体堆积的有机光催化剂。该材料在没有任何助催化剂的情况下，表现出了显著的光催化产氢性能，具有良好的稳定性和可循环性。通过时间分辨光致发光和电化学阻抗谱进一步评估了其光活性。该材料还通过降解有害有机染料亚甲基蓝表现出了高效的太阳光驱动光催化活性。
