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-, H2PO4-, NO3-, HSO4-, CH3COO-) by UV, NMR and fluorescence spectroscopy.
