A novel fluorescent chemosensor 2 exhibiting excited-state intramolecular proton transfer (ESIPT) process has been synthesized by condensation approach, among which 2 could be used as a multielement sensitive fluorescent probe for both Al3?+ and Cd2?+. The emission wavelength of 2 underwent blue shift of 78?nm upon binding with these ions. The cation-induced inhibition of ESIPT phenomenon was responsible for these fluorescence changes. Moreover, the absorption spectra of 2 showed changes with F? and AcO? ions also. TD-DFT studies well displayed the blue shift in the emission wavelength of 2 upon binding with Al3?+ ions.
