Photophysics and photochemical reactivities of organocopper(<scp>I</scp>) complexes. Crystal structure of [Cu₂(PPh₂Me)₄(µ,η¹-CCPh)₂]

Abstract

Dimeric [Cu2(PPh2Me)4(µ,η1-CCPh)2] has been synthesized and crystallographically characterized; its photophysics together with those of other related organocopper(I) complexes, [Cu2{2-C(SiMe3)2C5H4N}2] and [{Cu(C6H2Me3-2,4,6)}5] have been studied and Stern–Volmer quenching data of the phosphorescent state of the pyridine complex with organic halides are suggestive of a charge-transfer mechanism with a high driving-force regime.
