Click Chemistry: A Powerful and Versatile Methodology for Preparation of Ferrocene-Containing Polymers

Ferrocene-containing polymers (FcPs) have attracted much research interest in the last decade, due to their unique properties and enormous applications. However, it is a great synthetic challenge to prepare FcPs before the advent of click chemistry. In this review, we summarized the recent research efforts on synthesizing FcPs through click reactions, which include click modification of preformed polymers and click polymerization of ferrocene (Fc) containing monomers. Due to the containing Fc moieties, the FcPs enjoy excellent redox activity, thermal stability, electrochemical property, and magnetism. Accordingly, they are promising to be used as electrochemical sensors, catalysts, magneto-ceramics, electrode modifiers, optical devices, etc.
