Abstract
The photochemical behaviors of polyoxometalates (POMs) have been extensively studied and widely used in various photo-redox reactions. Incorporating photo-sensitive organic molecules onto the POM platform not only allows the rational design and fine-controlled synthesis of novel organic–inorganic hybrids but also gives the possibility to explore their potential applications in diverse areas such as photochromics, optical switching, and smart self-assemblies. Herein, we summarize the latest progress of photo-sensitive POM hybrids with a particular focus on the photo-induced reversible coloration, polymerization, and supramolecular self-assembly. The mechanisms and the crucial roles of POM clusters in such reversible processes are also considered.
