in the interior that strongly influenced their molecular recognition. Templates/guests with strong hydrogen-bonding groups in the midsection of the molecule benefited most, especially if the hydrophobe of the template could penetrate the amide layer to reach the hydrophobic core of the cross-linked micelles. The location and the orientation of the hydrophilic groups were also important, as they determined
当具有三丙炔铵头基和甲基丙烯酸酯官能化疏水尾部的表面活性剂在疏水模板分子存在下在表面和核心中以胶束形式交联时,制备了分子印迹纳米粒子(MINP)。由于表面活性剂在头基附近含有酰胺键,MINP 内部有一层氢键基团,这强烈影响它们的分子识别。分子中部具有强氢键基团的模板/客体受益最多,特别是如果模板的疏水基可以穿透酰胺层到达交联胶束的疏水核心。亲水基团的位置和方向也很重要,因为它们决定了模板如何与表面活性剂胶束相互作用,并最终与 MINP 受体相互作用。
