A near-UV triplet emission from Au(2)(dcpm)(2)(2) has been discovered. Studies on the spectroscopic properties of the complexes [Au(2)(dcpm)(2)]Y(2) (Y=ClO(4)(-), PF(6)(-), CF(3)SO(3)(-), Au(CN)(2), Cl(-), and I(-); dcpm=bis(dicyclohexylphosphanyl)methane) support the assignment of the high-energy emissions at 360-368 nm to the (3)[dsigma*psigma] excited state, adducts of which exhibit exciplex emissions in the visible region with solvent or counterions (see schematic diagram).
已发现Au₂(dcpm)₂₂的近紫外三重态发射。对配合物[Au₂(dcpm)₂]Y₂（Y = ClO₄⁻、PF₆⁻、CF₃SO₃⁻、[Au(CN)₂]⁻、Cl⁻和I⁻；dcpm = 双(二环己基膦基)甲烷）的光谱性质研究支持将360 - 368 nm处的高能发射归属于(³)[dsigma*psigma]激发态，其加合物与溶剂或抗衡离子在可见光区域呈现激基复合物发射（见示意图）。
