Terpyridine-based materials, metal coordination

Recently, the basic concept of self-healing metallopolymer networks was improved. For this purpose, the Schubert group utilized cadmium(ll)-bis-terpyridine complexes [101]. A metallopolymer network based on these complexes was synthesized by the addition of cadmium acetate. The authors could show that these materials behave completely different due to a different coordination of the metal center. Presumably, the acetate moiety also coordinates to the cadmium, but this metal-ligand interaction is much weaker, which results in an improved self-healing behavior (Fig. 7).
