The Letter is dedicated to the memory of Dr. J. M. Létoffé and Dr. B. Bonnetot Abstract—New thianthrene based macrocycles with basket shaped structures were prepared by thermal treatment of tetrakis-(N,N 0 -dimethylthiocarbamoyl)-tetra-tert-butyl-thiacalix[4]arene. Their structural characterization as well as the study of the formation mechanisms are presented in this article. The influence of the conformation of the starting thiacalixarene on the reaction is also discussed.
