Description
Summary:Hydrazone‐linked covalent organic frameworks (COFs) with structural flexibility, heteroatomic sites, post‐modification ability and high hydrolytic stability have attracted great attention from scientific community. Hydrazone‐linked COFs, as a subclass of Schiff‐base COFs, was firstly reported in 2011 by Yaghi's group and later witnessed prosperous development in various aspects. Their adjustable structures, precise pore channels and plentiful heteroatomic sites of hydrazone‐linked structures possess much potential in diverse applications, for example, adsorption/separation, chemical sensing, catalysis and energy storage, etc. Up to date, the systematic reviews about the reported hydrazone‐linked COFs are still rare. Therefore, in this review, we will summarize their preparation methods, characteristics and related applications, and discuss the opportunity or challenge of hydrazone‐linked COFs. We hope this review could provide new insights about hydrazone‐linked COFs for exploring more appealing functions or applications. This review provides an introduction on the recent progresses made in the field of hydrazone‐linked COFs for various applications including adsorption/separation, catalysis, chemical sensing and energy storage.
