摘要：

Calix[4]arene-5,11,17,23-tetrasulfonate (1) reacts with cerium(III) ion in alkaline solution to form a colored complex(lambda-max = 417 nm, epsilon = 1.09 x 10(4) 1 mol-1 cm-1). The coloration reaction is specific for cerium among rare-earth elements. The coloration mechanism was discussed on the basis of the stability constants.
