Abstract

The unprecedented, purely gold(I) alkynyl-diphosphine clusters 1–3 demonstrate intense room-temperature phosphorescence with maximum quantum efficiency of 92% in solution (3) and 86% in solid (2) and thermally dependent emission in the crystalline form, attributed to the crystal lattice arrangement.
