山东师范大学耿琰团队报道了自然光光催化合成用于光催化的苯并恶唑-桥联共价有机框架。相关研究成果发表在2022年10月10日出版的《美国化学会杂志》。

尽管自然光介导的光催化是一种清洁、高效、绿色的获取有机产品的方法，但其在共价有机框架（COFs）合成中的应用仍是前所未有的。

该文中，研究人员首次报道了环境条件下COF的太阳光光催化合成。此外，这种由苯并恶唑连接的COF产生的“窗台”反应是稳定的，可以用作可重复使用的光催化剂，以高度促进可见光驱动的硫化物好氧氧化为亚砜。这些结果不仅丰富了COF合成方法，而且为以绿色和可持续的方式获取COFs开辟了一条新途径。

Abstract: Although natural sunlight-mediated photocatalysis is a clean, efficient, and green approach to access organic products, its application in the synthesis of covalent organic frameworks (COFs), however, is still unprecedented. Herein, we first report the sunlight photocatalytic synthesis of COF under ambient conditions. Furthermore, this “window ledge” reaction generated benzoxazole-linked COF is stable and can be applied as a reusable photocatalyst to highly promote visible-light-driven aerobic oxidation of sulfides to sulfoxides. These results not only enrich the COF synthetic methodology but also open a new route to access COFs in a green and sustainable way.
