  • Title: An imidazole-functionalized polyacetylene: convenient synthesis and selective chemosensor for metal ions and cyanide.
    Author: Zeng Q, Cai P, Li Z, Qin J, Tang BZ.
    Journal: Chem Commun (Camb); 2008 Mar 07; (9):1094-6. PubMed ID: 18292901.
    Abstract:
    A new light-emitting polyacetylene bearing imidazole moieties in the side chain (), was conveniently prepared through a postfunctionalization 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 by Cu2+ could be turned on after the addition of CN-, making a novel, sensitive, and selective cyanide probe.
