Synthesis of a novel calix[4]arene-based fluorescent ionophore and its metal ions recognition properties

Abstract A novel fluorescent ionophore derived from calix[4]arene and pyrazoline was designed and synthesized. Its molecular structure was confirmed by 1 H NMR and element analysis. The resulting material shows specific fluorescent behavior toward the Zn 2+ ion among the other divalent metal ions, such as Co 2+ , Ni 2+ , Cu 2+ . The primary results indicate this ionophore material is a potential material for developing efficient fluorescent Zn 2+ chemosensors.
