Enantioselective wetting of a chiral polymer film was demonstrated. The contact angle of chiral liquids on the film was strongly dependent on their chirality although their physical properties including surface tension were identical. Such wetting behavior resulted from the enantioselective surface reorganization involving local conformational change of the polymer chains at the liquid interface. The concept of "dynamic interface for chiral discrimination" has possible potential for the development of materials capable of chiral sensing, optical resolution, and asymmetric synthesis.
手性聚合物膜的对映选择性润湿得到了证明。尽管手性液体的物理性质（包括表面张力）相同，但它们在薄膜上的接触角强烈依赖于它们的手性。这种润湿行为是由于在液体界面处涉及聚合物链局部构象变化的对映选择性表面重排引起的。“手性识别的动态界面”这一概念在手性传感、光学拆分和不对称合成等材料的发展方面具有潜在的可能性。
