Platinum-containing heterometallic metallacycles and metallacages

Coordination-driven self-assembly is one of the most powerful and efficient strategies to construct two- or three-dimensional discrete metallacycles and metallacages. Meanwhile, platinum(II)-based coordination is one of the most considerable ways to form the supramolecular systems because of its high stability and synthetic superiority. Among these metallacycles, heterometallic metallacycles possess rich photophysical and electrochemical characteristics, leading to applications in several fields, such as sensing and catalysis. In this chapter, we will thus focus on the construction of platinum-containing heterometallic metallacycles and metallacages and their potential applications. These assemblies were mainly constructed by the metalloligand approach, in which a metalloligand was prepared prior to the final self-assembly with another different metal. The self-sorting strategy was also occasionally used, enabling the one-pot synthesis of the final product from a multicomponent mixture containing different metals.
