Abstract
The novel o-phenylenediseleno bridged bis(cyclodextrin)s and its complexes with platinum(IV) and palladium(II) ions have been synthesized and characterized by elemental analyses, 1H NMR, infrared, and thermal analysis. Fluorescence spectrophotometric titrations have been performed in aqueous buffer solution (pH 7.20) at 25.0°C to give the complex stability constants (Ks) and Gibbs free energy change (-ΔG°) for the 1:1 inclusion complexation of natural β-cyclodextrin, the o-phenylenediseleno bridged bis(cyclodextrin)s 1 and its platinum(IV) complex 2 with 8-Anilino-1-naphthalenesulfonic Acid Ammonium Salt (ANS ammonium). The molecular inclusion ability of ANS ammonium by the three host compounds are discussed from the viewpoints of size/shape-fit concept and the multipoint recognition mechanism.
