Abstract

Abstract : Light-emitting tetramers of copper(i ) supported by pyrazolates with remarkable photophysical properties conducive to potential use in optoelectronic devices and/or sensors are reported. Abstract : Described herein is the synthesis and photophysics of two tetranuclear copper complexes, {[3, 5-(Pr i )2, 4-(Br)Pz]Cu}4 and {[3-(CF3 ), 5-(Bu t )Pz]Cu}4 tailor-designed by manipulating the pyrazolyl ring substituents. Unlike their trinuclear analogues, the luminescence of the tetranuclear species is molecular (not supramolecular) in nature with extremely high solid-state quantum yields of ∼80% at room temperature.
