Scissor-like Au₄Cu₂ Cluster with Phosphorescent Mechanochromism and Thermochromism.

ABSTRACT: Reaction of [Au(tht)₂](ClO₄) (tht = tetrahydrothiophene), [Cu(CH₃CN)₄](ClO₄), 3,6-di-tert-butyl-1,8-diethynyl-9H-carbazole (H₃decz), and bis(2-diphenylphosphinophenyl)ether (POP) in the presence of triethylamine (NEt₃) gave the cluster complex Au₄Cu₂(decz)₂(POP)₂ as yellow crystals. As revealed by X-ray crystallography, the Au₄Cu₂ cluster exhibits scissor-like structure sustained by two decz and two POP ligands and stabilized by Au-Cu and Au-Au interactions. The Au₄Cu₂ cluster shows bright yellow to orange photoluminescence upon irradiation at >300 nm, arising from ³[π (decz)→5d (Au)] ³LMCT (
