Synthesis, characterization, photophysics and electrochemistry of polynuclear copper(I) and gold(I) alkynyl phosphine complexes

A series of polynuclear copper(I) and gold(I) alkynyl complexes, [Cu3(μ-dppm)3(μ3-η1-CC-Np)2]BF4 (1), [Cu3(μ-dppm)3(μ3-η1-CCC6H4CN-4)2]BF4 (2) and [{AuP(Tol-p)3(CC)}2Np-1,5] (3), have been synthesized and shown to exhibit rich photoluminescence at ambient and low temperatures. The electrochemistry of the complexes has also been studied in detail by cyclic voltammetry.
