Abstract

A new azocalix[4]arene, 5,14,17,23-tetra[(2-benzoic acid)(azo)phenyl] calix[4]arene (2), has been prepared by hydrolysis of its ester derivative and characterized by ¹H NMR, IR, UV-Vis spectroscopy and elemental analysis. Based on UV spectral changes, we found that 2 exhibits Pb²⁺ ion selectivity. In basic media, Pb²⁺ forms a 1:1 complex with the ligand. Beer's law is obeyed in the range of 2.0 x 10^-6 - 2.4 x 10^-5 mol L^-1 of Pb²⁺. The molar absorptivity (ε) of 2-Pb²⁺ complex is 1.89 x 10⁴ L mol ^-1 cm^-1 at 440 nm, and the detection limit is 1.6 x 10^-6 mol L^-1.
