Luminescent molecular copper(I) alkynyl open cubes: synthesis, structural characterization, electronic structure, photophysics, and photochemistry.

A novel class of tetranuclear copper(I) alkynyl complexes with an "open-cube" structure was synthesized. The crystal structure of [Cu4{P(p-MeC6H4)3}4(mu3-eta(1),eta(1),eta(2)-C[triple bond]C-p-MeOC6H4)3]PF6 was determined. These complexes were found to display dual emission behavior.

Synthesis, characterisation, electrochemistry and luminescence studies of 9-anthrylgold(I) complexes.

Reaction of mono- and dinuclear gold(I) phosphine chloride precursors with an excess of organolithium reagent C14H9Li in dry diethyl ether or THF gave mononuclear [(PPh3)Au(C9H14)] and dinuclear [(P--P)Au2(C14H9)2] (P--P = dppm, dcpm) and [(dcpm)Au2Br(C14H9)], respectively. These complexes were found to be emissive both in the solid state and in fluid solutions.
