Coordination‐Driven Self‐Assembly of Arene–Ruthenium Compounds

Abstract The coordination‐driven self‐assembly of N‐donor ligands with dinuclear arene–ruthenium building blocks has allowed the construction of a wide range of cationic supramolecules with different architectures and functionalities. These supramolecules include (1) hexacationic molecular metallaprisms in which the size of the cycle and type of the arene–ruthenium acceptor and organic linker influence the antitumor behavior of the resulting self‐assembly, and (2) tetracationic molecular metallarectangles, which have host–guest capabilities and allow sensing of biological properties. This report covers the synthetic and structural aspects of these coordination‐driven self‐assembled supramolecules as well as their most promising applications, with a particular focus on potential biological, sensing, and host–guest applications.
