A new unsymmetrical azine derivative based on coumarin group as dual-modal sensor for CN− and fluorescent “OFF-ON” for Zn2 +

In this work, an unsymmetrical azine derivative chemosensor (YS) for respective recognition of CN− and Zn2 + was designed and synthesized. Sensor YS exhibited high sensitivity and good selectivity for cyanide and zinc in aqueous solution.39
