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.
