dc.description.abstract | The stoichiometry and binding constant of the paramagnetic lanthanide ion (Gd3+) with sulfonatomethylated calix[4]resorcinarene (H 8Xna4) were evaluated from the NMR relaxation data. Both 1H NMR spectroscopy and NMR relaxation data indicate that interaction of tetramethylammonium (TEMA) and N-methylpyridinium (MePy) cations with H 8Xna4 in the presence of Ln3+ (Lu3+ or Gd3+) results in the formation of ternary complexes [Ln(G)H 8X] with lanthanide ions, coordinated via sulfonate groups and organic cation included into the cavity of H8Xna4. The inclusion of long-chained N-decyl-(DePy) and N-cetylpyridinium (CPy) ions into H8Xna4 cavity leads to self-assembling which can be revealed by NMR relaxation method with Gd3+ probe ions. The excess of alkylpyridinium or TEMA cations leads to disassembling of (Gd) n(H8X)m(RPy)m aggregates. © 2004 Kluwer Academic Publishers. | |
