Abstract: The synthesis of 5,11,17,23-tetrakis(2-thiazole)azo-25,26,27,28-tetrahydroxy calixarene(Ⅰ) and 5,11,17,23,29,35-hexa(2-thiazole)azo-37,38,39,40,41,42-hexahydroxy calixarene(Ⅱ) was described. The structures were confirmed by IR, 1H NMR and elemental analysis. It was found that the synthesized derivatives have a good solubility in basic aqueous medium and posses molecular binding properties. It was showed that the derivatives exhibit a high selectivity for Ag+, Hg2+ and other ions compared with Na+, K+ and NH4+, which is because metal ions such as Ag+ and Hg2+ display a great affinity for soft coordination center of nitrogen and sulfur atoms.
