可见光介导的光催化有机转化作为一种替代热反应的方法引起了人们的极大关注。虽然已经开发了基于贵金属/有机染料的均相光催化剂，但它们的毒性和不可重复使用的性质使它们不适合大规模生产。因此，我们合成了一种三嗪和酮基功能化的非金属共价有机框架（TpTt）的多相光催化。由于该催化剂对可见光有明显的吸收，因此在宽基底范围的蓝光发光二极管存在下，通过能量转移过程，将其用于反式二苯乙烯向顺式二苯乙烯的光催化上坡转化。
Visible light-mediated photocatalytic organic transformation has drawn significant attention as an alternative process for replacing thermal reactions. Although precious metal/organic dyes based homogeneous photocatalysts have been developed, their toxic and nonreusable nature makes them inappropriate for large-scale production. Therefore, we have synthesized a triazine and a keto functionalized nonmetal based covalent organic framework (TpTt) for heterogeneous photo catalysis. As the catalyst shows significant absorption of visible light, it has been applied for the photocatalytic uphill conversion of trans-stilbene to cis-stilbene in the presence of blue light-emitting diodes with broad substrate scope via an energy transfer process.
