To develop sensitive and selective S2– chemosensors, a new disubstituted polyacetylene (P2) bearing pyridine moieties in the side chains was prepared conveniently through a postfunctional method, the strong green fluorescence of which could be completely quenched by Cu2+ ions at the concentration as low as 2.0 × 10–6 mol/L in diluted solutions. Based on the displacement strategy, by utilizing the much
