A series of trinuclear copper(I) thiolate complexes, [Cu3(
-dppm)3(3-SR)2]BF4 (R = C6H4Cl-4, C6H4CH3-4,C6H4OCH3-4, C6H4(OCH3)2-3,4, C6H4-benzo-15-crown-5, or tBu), [Cu3(-dppm)3(3-StBu)](BF4)2, and [Cu3(-dppm)3(3-SR)(3-Cl)]BF4 (R = C6H4CH3-4, C6H4tBu-4, or C6H4(CH3)3-2,4,6) and two hexanuclear copper(I)selenolate complexes, [Cu6(-P
P)4(3-SePh)4](BF4)2 (PP = dppm, (Ph2P)2NH), have been synthesized, andtheir photophysical properties have been studied. The X-ray crystal structures of both copper(I) selenolate complexeshave been determined. These complexes have been shown to exhibit long-lived low-energy emission in solution,attributed to an excited state of predominantly ligand-to-metal charge-transfer [chalcogenolate to copper(I)] origin.
