A series of gold- and silver-containing ionic liquids, [CnMIM][M(CN)2] (M = Au, Ag; n = 12, 14, 18), prepared by metathesis reactions, present luminescence depending on their physical state i.e. crystalline or smectic A phases. The photoluminescent measurements as well as DFT calculations suggest that the modulation of aurophilic intermolecular interactions are responsible for this phosphorescent behaviour.
通过复分解反应制备的一系列含金和银的离子液体,[CnMIM][M(CN)2] (M = Au, Ag; n = 12, 14, 18),根据其物理状态呈现发光即结晶相或近晶A相。光致发光测量以及 DFT 计算表明,亲金分子间相互作用的调节是造成这种磷光行为的原因。
