摘要

共价有机框架（COFs）作为一类非均相光催化剂，在有机分子的合成和功能化中表现出环境友好的特点。本研究合成了三种噻吩基供体-受体（D-A）型COFs，并对其光电性能和光催化性能进行了研究。利用这三种COFs，我们首次开发了非均相COFs光催化硫醇脱氢交叉偶联制备不对称二硫化物。该方法显示出广泛的衬底范围。该方法的特点是使用COFs作为可回收的异相光催化剂，可见光作为光源，空气作为清洁的氧化剂，乙醇作为绿色溶剂，为获得有价值的二硫化物提供了有希望的途径。

Thiophene-based covalent organic frameworks for heterogeneous photocatalytic synthesis of unsymmetric disulfides

Covalent organic frameworks (COFs), as a class of heterogeneous photocatalysts, exhibit environmentally friendly characteristics in the synthesis and functionalization of organic molecules. In this study, three thiophene-based donor-acceptor (D-A) type COFs have been synthesized, and their optoelectronic properties and photocatalytic performance have been studied. Using the three COFs, we have developed the first heterogeneous COFs photocatalyzed dehydrogenative cross-coupling of thiols to produce unsymmetrical disulfides. The approach has shown a broad substrate scope. Featured by employing COFs as a recyclable heterogeneous photocatalyst, visible light as a light source, air as a clean oxidant, and ethanol as a green solvent, this methodology offers promising access to valuable disulfides.
