Abstrakt: The first fluorine-containing cryptand F3-TREN 4 for the complexation of anions was prepared in the 3 + 2-condensation reaction of 2-fluoro-1,3-phthalaldehyde 3 with tris(2-aminoethyl) amine and subsequent reduction with NaBH4. Upon incorporation of anionic guests 4 ·6HClO4experiences shifts of its 19F NMR resonances and thus demonstrates the advantages of studying host-guest association by 19F NMR spectroscopy.
