Selective fluoride ion recognition by a thiacalix[4]arene receptor containing N-(4-nitrophenyl)acetamide and 1-amidoanthraquinone fragments

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.
