Abstract

The complex [Au₂(dppm)₂]²⁺ [dppm = bis(diphenylphosphino)methane] exhibits a long-lived room temperature photoluminescence in fluid solutions (emission maximum, 565 nm; τ₀, 17.0 μs; Φ_em, 0.15); the phosphorescent excited state of [Au₂(dppm)₂]²⁺ undergoes oxidative and reductive quenching with methyl viologen and N,N,N′, N′-tetramethyl-p-phenylenediamine, respectively, and can be quenched by organic halides.
