Synthesis and fluorescence sensing properties of a new naphthalimide derivative of calix[4]arene

A new naphthalimide derivative of calix[4]arene was synthesized as a highly selective fluorescent compound for Cu2+ among the selected metal ions. This compound was examined for its fluorescent properties toward different metal ions (Na+, Li+, Mg2+, Ni2+, Ba2+, Ca2+, Cu2+, Pb2+, Zn2+) and anions (F−, Cl−, Br−, H 2 PO 4 - , NO 3 - , I−, HSO 4 - , CH3COO−) by UV, NMR and fluorescence spectroscopy.
