Recent research progress in the synthesis, properties and applications of ferrocene‐based derivatives and polymers with azobenzene

Abstract

Aromatic azobenzene derivatives are outstanding organic photochromic compounds that possess unique photochemical properties. These compounds are widely used in research and development for various applications, especially in information storage, owing to their ability to isomerize between cis (Z) and trans (E) forms under the influence of light of different wavelengths. On account of these advantages, many efforts have been made to generalize the use of azobenzene derivatives. Furthermore, ferrocene‐based polymers and derivatives are promising candidates for functional materials due to their unique redox properties. By interlinking ferrocene with azobenzene, novel functional materials can be obtained that will integrate the excellent properties of both and will provide new applications in various fields including information storage, ion recognition, molecular devices, etc. This article provides an overview of the synthesis, properties and applications of novel ferrocene‐based polymers and derivatives containing azobenzene units.
