Development of a coordination chemistry-based approach for functional supramolecular structures

The weak-link approach (WLA) to supramolecular assemblies allows for the design of multimetallic two- and three-dimensional arrays, host-guest architectures, sensors, catalysts, switches, and signal amplification devices. This Account describes the course of our investigations in this area beginning with the development of a chemical tool kit Of building blocks consisting of multiple metals and ligands. These building blocks can be rationally mixed and matched to provide structures with a vide range of properties that have been used to develop functional supramolecular architectures, including chemical sensors and allosteric catalysts.
