A new light-emitting polyacetylene bearing imidazole moieties in the side chain (P1), was conveniently prepared through a post-functionalization strategy, as a sensory polymer to selectively report the presence of Cu2+ (with a detection limit of 1.48 ppm) based on the fluorescence turn-off''. Interestingly, the quenched luminescence of P1 by Cu2+ could be turned on after the addition of CN-, making P1 a novel, sensitive, and selective cyanide probe.
