互补氢键在空气-水界面有效地起作用，用于水溶性客体的特异性结合。因此，双链肽两亲物的单组分和混合单分子膜显示通过疏水和氢键相互作用将水溶性二肽选择性地掺入到在单分子膜的极性肽区域产生的特定空腔中。在混合单分子膜中产生受体位点的"诱导适应"机制是可以想象的。氢键相互作用也适用于在水分子上制备精确的图案。胍盐和三聚氰胺单分子膜中的分子排列分别通过与聚羧酸盐和巴比妥酸结合来控制。多功能客体如FAD可以诱导分子模式。这些结果的影响进行了讨论。
Complementary hydrogen bonding acts efficiently at the air water interface for specific binding of aqueous guests. Thus, single-component and mixed monolayers of double-chain peptide amphiphiles displays selective incorporation of water-soluble dipeptides via hydrophobic and hydrogen-bonding interaction into the specific cavities created at the polar peptide region of monolayers. An ''induced fit'' mechanism is conceivable for the generation of receptor sites in mixed monolayers. The hydrogen-bonding interaction is also applicable to the preparation of molecularly precise patterns on water. The molecular arrangement in guanidinium and melamine monolayers is controlled through binding with polycarboxylates and barbituric acid, respectively. A multi-functional guest like FAD can induce molecular patterns. Implications of these results are discussed.
