| Abstract: | A new chemosensor was synthesized by the alkylation of p-tert-butyl-calix4]arene with three N,N-diethylacetamide groups and one methyl 3-ethoxy-naphthalene-2-carboxylate, which exhibited highly selective fluorescent response to Pb2+ over alkali, alkali earth metal ions and some transition metal ions in CH3CN-H2O. |
