Electrofluorochromic detection of cyanide anions using a benzothiadiazole-containing conjugated copolymer†
Abstract
Selective detection of cyanide anions is realized via electrofluorochromism of a benzothiadiazole-containing conjugated copolymer because oxidative fluorescence quenching induced by positive potentials can be significantly weakened by interaction between nucleophilic cyanide and electron-deficient benzothiadiazole.
