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

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. (C) 2008 Qiang Peng.
