Steric augmentation of three-coordinate Cu( i ) β-diketiminate isocyanide chromophores to achieve microsecond excited-state lifetime

Key Points

To investigate the effects of steric augmentation on excited-state lifetimes in copper(i) complexes.
Modified the steric profile of the β-diketiminate ligand and m-terphenyl isocyanide.
Analyzed the excited-state lifetimes of the resulting heteroleptic copper(i) complexes.
Achieved excited-state lifetimes in the microsecond range for some complexes.
Showed significant improvements due to steric modification.

Abstract

Augmenting the steric profile of both the β-diketiminate ligand and the m -terphenyl isocyanide increases the excited-state lifetime in heteroleptic copper( i ) complexes, reaching the microsecond range in one case.
