Chemical Research in Chinese Universities Aims and scope

Abstract

A well-known deep-blue emitting iridium(III) complex was selected for deuterium isotope effect evalua-tion, both on deuterated locations and numbers, through theoretical investigation. It was revealed that the containment of the d site deuteriation of ancillary ligand picolinate enabled the non-radiative deactivation process to be repessed, and thereby improving the quantum efficiency through such a simple and controllable approach.
