A direct nitration of the upper rim of thiacalix [4]arenes is not possible due to the undesirable oxidation of the sulphur atoms during the nitration step leading to very complicated reaction mixtures. On the other hand, thiacalix[4]arene derivatives can be at first transformed intentionally to the
