Abstract

Abstract : A dual-channel sensor (T ) based on a phenazine derivative has been designed and synthesized. The sensorT could successively detect CN − and HSO4 − in aqueous solution with high selectivity and sensitivity. Abstract : A dual-channel sensor (T ) based on a phenazine derivative has been designed and synthesized. The sensorT could successively detect CN − and HSO4 − in aqueous solution with high selectivity and sensitivity. Upon the addition of water solution of CN −, the sensorT showed an immediate visible color changes from yellow to orange, meanwhile, the yellow fluorescence of sensorT quenched. More interestingly, the color and fluorescence could be recovered upon the addition of HSO4 − into the CN − contained sensorT solutions. Other anions couldn't induce similar response. The detection limits ofT to CN − andT + CN − to HSO4 − were estimated to be 8.90 × 10 −8 M and 1.46 × 10 −10 M, respectively. Notably, this successive response feature of sensorT makes it has a potential utility for CN − and HSO4 − detection in aqueous solution.
