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-S^tBu)](BF₄)₂, and [Cu₃(-dppm)₃(₃-SR)(₃-Cl)]BF₄ (R = C₆H₄CH₃-4, C₆H₄^tBu-4, or C₆H₄(CH₃)₃-2,4,6) and two hexanuclear copper(I)selenolate complexes, [Cu₆(-PP)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.
