Abstract
Hydrazone-based covalent organic frameworks (COFs) are rich in functional groups but have very limited variety and applications. Herein, two hydroxy-rich hydrazone-based COFs are synthesized in pure water and postsynthetically incorporated with CoII, exhibiting Lewis acid catalytic activity towards cyanosilylation of various aldehydes with size selectivity.
摘要
基于腙的共价有机框架（COFs）富含官能团，但种类和应用非常有限。在此，在纯水中合成了两种富含羟基的腙基 COFs，并进行了后合成钴(II)掺入，对各种醛的氰硅烷化反应具有路易斯酸催化活性，并具有尺寸选择性。
