Abstract

Implementing high quantum yields and long-lived excited state lifetimes within heteroleptic luminescent Cr^III complexes is a keystone for the design of supramolecular energy-converting devices exploiting this cheap metal. In this contribution, we discuss the stepwise and rational optimization of these two limiting factors within a series of heteroleptic Cr^III complexes.
