A Thiacalixarene is a macrocycle or cyclic oligomer based on a condensation product of a phenol derivative and sulfur. The word thiacalixarene is derived from thia (as sulfur) and calixarene. Thiacalixarenes have hydrophobic cavities that can hold smaller molecules or ions and belong to the class of cavitands known in host–guest chemistry. Thiacalixarene nomenclature is straightforward and involves counting the number of repeating units in the ring and include it in the name. A calix[4]arene has 4 units in the ring and a calix[6]arene has 6.

The defect that the lower-edge modifying structure of thiacalix[4]arene is single is overcome. According to the thiacalix[4]arene acylhydrazone Schiff base derivative, acylhydrazone Schiff base is introduced to the lower edge of thiacalix[4]arene to form a drooping chelating arm, and the selective complexing capability of the thiacalixarene derivative on metal ions is enhanced by means of the synergistic effect of the drooping chelating arm and thiacalixarene holes. Results of preliminary experiments on the properties of the compound show that the thiacalix[4]arene acylhydrazone Schiff base derivative has the good recognition capability on the metal ions.
