Versatile heteroleptic bis-terdentate Cr(III) chromophores displaying room temperature millisecond excited state lifetimes

Author affiliations

Abstract

Substitution of Ru(II)-based chromophores with cheaper Cr(III)-based complexes in optically active metallo-supramolecular architectures is limited by the lack of synthetic strategies leading to heteroleptic Cr(III)-polypyridyl complexes with long excited-state lifetimes. Herein, we report on a versatile method yielding heteroleptic bis(terdentate) Cr(III) complexes with room temperature millisecond range excited-state lifetimes, tuneable electronic and photophysical properties and easy anchoring possibilities.
