A highly selective coumarin-based chemosensor for naked-eye detection of cyanide anions via nucleophilic addition in pure aqueous environment

A benzothiazole-based new fluorogenic chemosensor for the detection of CN− and its real-time application in environmental water samples and living cells

“…[24][25][26][27][28][29][30][31][32][33][34][35][36][37] The reported cyanide uorescence sensors involved the following mechanistic concepts: coordination, hydrogen bonding interaction, anion-metal affinity, nucleophilic addition reactions, and based on nanotechnology. 32,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] Hydrogen bonding, anion metal affinity, and coordination sensors all have signicant drawbacks, including a lack of selectivity and interference from competing analytes such as uoride, phosphate, and acetate ions. However, among the numerous chemosensors described, reaction-based sensors (chemodosimeters) offer the benets of high specicity, outstanding sensitivity, and rapid response time.…”
