中文摘要	based on a specific nucleophilic addition reaction with cyanide, a dicyano-vinyl-containing conjugated polymer (p1) has been designed and synthesized as a colorimetric and fluorescent chemosensor for cyanide anion. the combination of advantages of both reaction-based sensors and conjugated polymer sensors offers its highly sensitive and selective recognition of cn(-). the addition of cn(-) to p1 solution induced a change in the solution color from yellow-green to colorless, while no color change could be observed in presence of other common anions, by which cn(-) can be identified from other anions directly with the naked eye. at the same time, a 31.6-fold fluorescence quenching was achieved upon adding cn(-) into p1 solution. the fluorescence quenching has shown a linear response to cn(-) in the concentration range of 0.5-30 mu m. furthermore, its detection limit for cn(-) can be as low as 14 ppb, which is among the best results for the fluorescent conjugated polymer-based cyanide chemosensors. compared with its small molecular counterpart, p1 exhibits higher sensitivity and selectivity, wider linear region, and faster response.
