Abstract: 選択的な分子認識能を示す人工材料として, 分子インプリント法に基づく種々の応用技術を開発し, その分子選択的な吸着能評価及び環境汚染物質の分析前処理剤としての可能性を評価した. 目的物質の構造の一部あるいは類似物質を擬似的な鋳型分子として用いるフラグメントインプリント法やイオン性官能基の官能基間距離認識を可能とする新規方法論により得られた分離媒体によって, 内分泌撹かく乱化学物質, ハロゲン化芳香族, 水溶性天然毒物などの選択的分離/濃縮が達成された. さらに, 官能基間距離認識の応用として, 光触媒性酸化チタン上へ認識部位を導入することで, 水環境中の毒性物質の選択的捕捉・光分解が達成された.
The application techniques based on the molecular imprinting for selective molecular recognition were developed, and we evaluated newly developed separation media concerning its fundamental retention properties and the possibilities as pretreatment media of environmental pollutants. Selective separation and/or concentration of environmental pollutants such as endocrine disrupters, halogenated aromatic compounds, and water-soluble natural toxins was achieved by newly proposed techniques, the fragment imprinting and the interval immobilization technique. Furthermore, the selective adsorption and photo degradation of natural toxin in environmental water was demonstrated by the hybrid material of titanium oxide nano particles modified with interval immobilized recognition site.
