A novel conjugated polyelectrolyte P1, having a meta-substituted monopyridyl in the backbone, is designed and synthesized for Ag(+) detection in aqueous solution. As a chemosensor, P1 shows high sensitivity, low detection limit, and excellent selectivity for Ag(+) over other metal ions. The sensing mechanism is based on the specific interaction between Ag(+) and the pyridyl group of P1. The aggregated state of the polymer in water can amplify its quenching efficiency.
一种新型的共轭聚电解质 P1，在主链上具有一个间位取代的单吡啶基，被设计和合成用于在水溶液中检测 Ag(+)。作为一种化学传感器，P1 对 Ag(+)具有高灵敏度、低检测限和优异的选择性，优于其他金属离子。传感机制基于 Ag(+)与 P1 的吡啶基团之间的特异性相互作用。聚合物在水中的聚集状态可以放大其猝灭效率。
