New derivatives of thiacalix[4]arene, tri- and tetrasubstituted at the lower rim by N-(4-nitrophenyl)acetamide and 1-amidoanthraquinone fragments were synthesized. Their ability for recognition and binding of some anions (F–, Cl–, Br–, I–, MeCO2-, H2PO4-, NO3-) was examined by UV spectroscopy, and a selective receptor for fluoride ion giving a 1 : 1 complex was invented.
