| 摘 要： | 具有较高荧光量子产率,并且在水溶液中聚集很弱的阳离子型水溶性聚对芳撑乙炔(P1)是一种潜在的高灵敏荧光传感材料.通过比较研究多价无机抗衡离子和具有表面活性剂性质的抗衡离子对P1聚集态的影响,以及P1与3个具有相似结构的有机小分子猝灭剂之间的荧光猝灭效应,深入探讨了水溶性共轭聚合物荧光猝灭传感的猝灭剂构效关系.

| Abstract: | Cationic water-soluble poly(aryleneethynylene)s (P1) is a potential highly sensitive fluorescent sensory material due to its high photoluminescent quantum yield and minimal aggregation in water. In this paper, the effects of multivalent inorganic counterions and surfactant on the aggregation and fluorescence quenching of P1 were studied in water. Moreover, interactions between P1 and three organic quenchers with analogous structures were investigated. Thus, this paper provided some insights into the relatio... |
