An intensely and oxygen independent phosphorescent gold(i)–silver(i) complex: “trapping” an Au8Ag10 oligomer by two gold-alkynyl-diphosphine molecules†
Abstract
The molecular heterometallic [{Au8Ag10(C2Ph)16}{(PhC2Au)2PPh2(C6H4)3PPh2}2]2+ aggregate of unprecedented topology was obtained and structurally characterized; this compound demonstrates unusually effective phosphorescence, which displays negligible oxygen quenching due to shielding of emissive central cluster by the outer shell of the molecule.
