The synthesis of tetrathiacalix[4]arene was achieved by the detertiobutylation of p-tert-butyltetrathiacalix[4]arene. X-ray diffraction studies revealed that in the solid state whereas p-tert-butyltetrathiacalix[4]arene forms inclusion complexes with solvent molecules, tetrathiacalix[4]arene undergoes self-inclusion leading to trimeric units. The same behaviour in the crystalline phase was also demonstrated for calix[4]arene. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
