Abstract

A soft salt, S, comprising two oppositely charged platinum(II) complexes, ([Pt(C_F₂^N)(en)]⁺ and [Pt(C_Ph₂^N)(CN)₂]⁻), was synthesized and characterized. Compound S exhibits photoluminescence in DMSO solution, emitting at 558 nm upon excitation at 414 nm, with a quantum yield of 0.49. In the solid state, when dispersed in a KBr matrix, a broad emission band centered at 658 nm is observed. The cationic and anionic components of S interact through electrostatic and van der Waals forces, leading to pronounced modifications of their luminescent behavior compared to their isolated counterparts. These include vapochromic responses, reversible photoluminescence quenching upon exposure to acid vapors, and thermally induced luminescence enhancement.

具有多刺激响应特性的环金属化铂（ii）配合物软盐

合成了一种软盐S，由两个相反电荷的铂（II）配合物([Pt(CF2^N)(en)]+和[Pt（CPh2^N)(CN)2]−）组成。化合物S在DMSO溶液中表现出光致发光，在414 nm激发时发光波长为558 nm，量子产率为0.49。在固体状态下，当分散在KBr基体中时，观察到以658nm为中心的宽发射带。S的阳离子和阴离子组分通过静电和范德华力相互作用，导致它们的发光行为与孤立的对偶物相比有明显的改变。这些包括气相变色反应，暴露于酸性蒸气时可逆的光致发光猝灭，以及热致发光增强。
