In the past few years, a new family of supramolecular metallodendrimers, which possess cavities with well-defined shape and size, have attracted widespread attention. Coordination-driven self-assembly has proven to be a simple and highly efficient approach for the preparation of cavity-cored supramolecular metallodendrimers. This feature article focuses on the recent progress in the construction of a variety of cavity-cored supramolecular metallodendrimers via coordination-driven self-assembly. The characterization and hierarchical self-assembly behaviour of such metallodendrimers are also discussed.
