Abstract A novel acylhydrazone-based fluorescent probe HL was synthesized and characterized by 1H NMR, 13C NMR, mass spectrum (MS) and x-ray diffraction analysis. HL showed high selectivity and sensitivity towards Al3+ over other metalions based on excited-state intramolecular protontransfer (ESIPT) and photo-inducedelectrontransfer (PET) processes with a low detection limit (2.14 × 10−8 M) and
