Photoluminescent Cu(i) vs. Ag(i) complexes: slowing down emission in Cu(i) complexes by pentacoordinate low-lying excited states

Dalton Trans. 2019 Jul 2;48(26):9765-9775. doi: 10.1039/c9dt00772e.

Abstract

This work describes the synthesis, and structural, spectroscopic, and theoretical studies of a mononuclear silver(i) complex with the formula [Ag(Xantphos)(4,4'-(MeO)2-2,2'-bipy)]BF4·DCM (1·BF4) [Xantphos: 4,5-bis(diphenylphosphino)-9,9'-dimethylxanthene]. We provide meaningful insights into the enhancement of the photoluminescence features of this silver(i) complex compared to its copper(i) analogue.
