Synthesis, characterization, structure and luminescence studies of mono-, di- and trinuclear gold(I) phosphine alkynyl complexes

A series of luminescent gold(I) phosphine mono- and diynyl complexes with nuclearity ranging from one to three has been synthesized and characterized; one of them have its crystal structure determined. Their photophysical properties have been studied and emission origin elucidated. (C) 2003 Elsevier B.V. All rights reserved.
