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

摘要

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 center dot DCM (1 center dot 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.
