Outline of Final Research Achievements |
A method was developed for the analytical determination of rate constants of intermolecular interactions and those of solute permeation at the interface of molecular aggregates. High performance liquid chromatography was used for measuring experimental data, which were analyzed on the basis of the moment theory. To demonstrate the effectiveness of the method, it was applied to some concrete experimental systems. Compared with conventional methods, some items of information about intermolecular interactions can be obtained more accurately by the method because neither immobilization nor fluorescence labelling of solute and ligand molecules is required. Interfacial solute permeation can also be analyzed under the preferable conditions that molecular aggregates originally should be. Moment equations required for the analysis of experimental data were also developed.

Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した化学現象解析法では、溶質やリガンド分子の固定化や蛍光標識化が不要であるため化学的に非修飾の遊離分子間における本来の相互作用情報を解析することができる。また、分子集合体に何等かの化学修飾や物理作用を加えることなく、分子集合体が本来あるべき状態により近い条件下における界面物質透過現象の解析が可能である。汎用性の高いHPLCのみを使用するため、化学現象解析の機会を広く数多くの研究者や技術者に提供し、関連研究の推進に寄与するものと期待される。さらにこれまで分離分析法として利用されてきたHPLC機能を分離分析とは異なる化学特性解析の新たな領域へと拡張する。
