The photophysical and luminescence quenching properties of a platinum(II) acetylide-based conjugated polyelectrolyte, Pt-p, which features carboxylic acid solubilizing groups are reported. The Pt-acetylide polymer is water soluble, and it exhibits phosphorescence from a triplet pi,pi exciton based on the conjugated backbone. The phosphorescence from Pt-p is quenched by viologens with different charges
报道了基于铂 (II) 乙炔化物的共轭聚电解质 Pt-p 的光物理和发光猝灭特性,该电解质具有羧酸增溶基团。Pt-乙炔聚合物是水溶性的,它表现出来自基于共轭骨架的三线态 pi,pi 激子的磷光。来自 Pt-p 的磷光被具有不同电荷(MV(+)、MV(2+) 和 MV(4+))的紫罗碱淬灭,并且在每种情况下,淬灭都由动态(扩散)机制主导。将 Pt-p 的 Stern-Volmer 猝灭性质与结构类似的荧光有机聚电解质的性质进行比较,得出的结论是,荧光共轭聚电解质通常观察到的放大猝灭效应,
