Abstract:
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.
