Summary: A versatile mono-Schiff compound ABJ-MS was synthesized easily using a one-step reaction. ABJ-MS exhibited diverse fluorescence responses to Zn2+/Al3+/Fe3+/Ag+ addition, with the maximum fluorescence emission undergoing a hypsochromic shift and fluorescence enhancement. However, Cu2+ addition resulted in fluorescence quenching. ABJ-MS also displayed distinct absorption changes and had the potential to mimic versatile logic circuits based on metal ion-mediated optical responses.
