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 ($\mathrm{F^-}$, $\mathrm{Cl^-}$, $\mathrm{Br^-}$, $\mathrm{I^-}$, $\mathrm{MeCO_2^-}$, $\mathrm{H_2PO_4^-}$, $\mathrm{NO_3^-}$) was examined by UV spectroscopy, and a selective receptor for fluoride ion giving a $1:1$ complex was invented.
