title: An anion-conjugated polyelectrolyte designed for the selective and sensitive detection of silver(I).
abstract: 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.
