多座の配位子とハロゲン化物イオンとを含む混合配位子錯体の生成平衡を系統的に検討した.得られた結果を基に,ルイス酸を含むレセプターによる陰イオンの分離・検出を試み,次のような成果を得た.(1)フッ化物イオンの比色及び蛍光定量に用いられてきた反応の平衡を解明するとともに,新しい反応系を開発した;(2)金属イオンのキレート抽出及びキレート樹脂への吸着を陰イオンが促進する機構を解明した;(3)Zr(IV)の高分子錯体を用いてフッ化物イオンを選択的に吸着・濃縮できること,又陰イオンをイオンクロマトグラフ分離できることを示した;(4)フッ化物イオンの電位差定量を妨害する金属イオンに対するマスキング剤を選択する際の基準を明らかにした.Systematic equilibrium studies were carried out on the formation of mixed-ligand complexes with multidentate ligands and halides. Based on the obtained results, the separation and detection of anions were examined with new receptors containing Lewis-acidic centers: elucidation of the reactions used for colorimetry and fluorometry of fluoride and developement of new reaction systems; elucidation of the effects of anions on the extraction of metal ions and on their adsorption to chelating resins; the application of polymer complexes of Zr(IV) as an adsorbent for fluoride and as a stationary phase for immobilized metal affinity chromatography; the establishment of criteria for selecting the masking reagent in the potentiometric determination of fluoride

Interaction of anions with receptors containing a Lewis acid and its application to separation and detection of anions.
