Phenazine-based colorimetric and fluorescent sensor for the selective detection of cyanides based on supramolecular self-assembly in aqueous solution

In this paper, a fluorescent and colorimetric sensor based on the mechanism of the deprotonation process and the supramolecular self-assembly was designed and synthesized, which could detect CN− in aqueous solution for a moment with high sensitivity and selectivity. It had a remarkable ON-OFF type fluorescent signaling behavior and obvious color change from yellow to jacinth by added CN− into the solution of ZL.88
