New fluorescence chemosensors (CS1 and CS2) based on flavonol derivatives were successfully synthesized and characterized. Complexation behaviour of sensors towards zinc and other tested metals have been studied using UV-vis and fluorescence spectrometric methods. These reveal selective detection towards Zn2+ ion, along with fluorometric response. Also, those serve as a highly selective chemodosimeter for Zn2+ at neutral pH with naked-eye detection and successfully examined the reversibility of chemosensor-Zn(II) complexation.
