چکیده انگلیسی
A simple colorimetric and turn-on fluorescence receptor 1 was prepared and its cations and anions sensing properties were investigated in CH3CN solution. Receptor 1 can selectively sense F− and CN− based on distinct color changes among a series of ions. Receptor 1 displayed a highly selective colorimetric response to fluoride anions based on a hydrogen bonding interaction process and fluorescent with colorimetric response to cyanide anions based on a generation of a cyanide adduct. The detection limit of receptor 1 toward F− and CN− ion was determined to be 0.28 ppm and 0.41 ppm, respectively. The two detection limit values were sufficiently low to detect submicromolar concentration of the F− and CN−.
