摘要：

A series of luminescent tetranuclear cuboidal copper(I) diynyl complexes, [Cu-4(PAr3)(4)(mu(3)-eta(1)-C=C-C=CR')(4)] (Ar = Ph, R' = Ph, C6H4CH3-p, C6H4OCH3-p: Ar = C6H4CH3-p, C6H4F-p. R' = Ph) has been synthesized and characterized. The X-ray crystal structure of [Cu-4(PPh3)(4)(mu(3)-eta(1)-C=C-C=CPh)(4)] has been determined. The origin of the low-energy emission in the complexes is assigned as derived from a metal-centered 3d(9)4s(1) state, mixed with LMCT [diynyl --> Cu-4] and IL [pi-pi*(diynyl)] states.
