The synthesized Schiff base ligand 3-hydroxy-N'-(2-hydroxy-3-methoxybenzylidene)-2-naphthohydrazide (H2NPV) is structurally characterized by single-crystal X-ray diffraction (XRD) and exhibits weak fluorescence in the excited state owing to the effect of excited-state-induced proton transfer (ESIPT). However, in the presence of Al3+, the ESIPT is blocked and chelation-enhanced fluorescence (CHEF) is induced because of complexation with the cations, resulting in turn-on emission for Al3+. The probe H2NPV selectively detects Al3+ among
