Novel chemosensors based on 2-(2′-hydroxyphenyl)-4-phenylthiazole were synthesized and their anion sensing behaviors were investigated. Sensors 1 and 2 show fluoride ion selective behaviors related to their absorption and emission spectra amongst F-, CH3CO2-, H2PO4-, Cl-, Br-, I-, ClO4-, NO3-, and HSO4- anions. Sensor 2 shows color change upon interaction with F-. Interactions of 1, 2 and 3 with F- cause a red-shift in UV-vis absorption and a large Stokes shift in fluorescence emission due to the inhibition of ESIPT induced by the deprotonation of phenolic proton by F-.
