synthesis of a series of carbazole–triazine based donor–acceptor (D–A) POFs and their photocatalytic activities for aerobicoxidation reactions. The simultaneous introduction of a carbazole-based electron donor and a triazine-based electron acceptor in D–A POFs stabilizes the charge transfer state and enables an efficient triplet–triplet energy transfer to generate 1O2. Meanwhile, systematic variation of
我们报告了一系列基于咔唑-三嗪的供体-受体(DA)POF的合成及其对需氧氧化反应的光催化活性。在D–A POF中同时引入咔唑基电子供体和三嗪基电子受体可稳定电荷转移状态,并能有效地进行三重态-三重态能量转移,从而产生1 O 2。同时,D–A距离的系统变化导致可调节的光氧化还原特性,因此产生了活性氧(ROSs)的效率。在可见光激发下,所有三种D–A POF均具有出色的促进三种需氧氧化的能力:硫化物氧化,氧化胺偶联和曼尼希反应。这项系统的研究验证了D–A POF作为高性能光氧化催化剂的设计原理,该催化剂具有广泛的底物范围以及出色的稳定性和可回收性。
