Arborols Based on Luminescent and Redox‐Active Transition Metal Complexes

Abstract

Not an electronic circuit, but a chemical formula of a huge metal complex is depicted here. The circles stand for metal centers, the zigzags for bridging ligands, and the dashes for terminal ligands. The Ru22 complex, which belongs to the class of cascade compounds (arborols/dendrimers), is the largest Werner-type complex so far.
