Abstrakt: A novel cyanine compound based on the conjugated perylene-benzothiazole system (PBI) as a colorimetric and fluorometric dual-channel sensor for cyanide (CN - ) detection was synthesized and characterized via UV-vis and fluorescence spectroscopy. PBI exhibited a high sensitivity and rapid optical response for CN - due to the intramolecular charge transfer (ICT) mechanism. The detection limit of PBI for CN - was 1.15×10 -7  M in the mixture of DMSO/H 2 O (1 : 1, v/v). Moreover, probe PBI demonstrated high selectivity and sensitivity for CN - over other common anions, including Cl - , Br - , F - , I - , AcO - , ClO 4 - , HSO 4 - , SO 4 2- , NO 2 - , NO 3 - and SCN - . This work provided a simple and effective approach to trace the toxic CN - ion with rapid response, high selectivity, and sensitivity that is possibly applied in environmental control and agricultural management.
