The incorporation of metal complexes into polymers leads to functional materials; whereas, the properties of polymers – easy processability, light weight or the adjustable molar mass – and those of metal complexes – optical properties, catalytic activity or biomedical potential – can be combined. Through the years, various different applications have been developed, depending on the needs of current techniques and society. Thus, advanced applications enabled by metallopolymers, include areas: like self-assembly, stimuli-responsive behavior, catalysis, optics, self-healing, shape-memory as well as biomedicine and further potential applications can be expected. In the review by Schubert et al (Prog. Polym. Sci., 2021, 119, 101428), This review will summarize and discuss these applications as well as how the interactions of metal complexes and polymers enable them.
