Hierarchical Mesoscopic Structures of Polymer Complexes

本研究是表面分析物理学家和薄膜制备高分子化学家的合作研究。本研究的目的是利用分子和分子组装的自组装和自组织，从纳米尺度到微米尺度的二维聚合物配合物的分层结构。在金表面制备了自组装的核碱基两亲分子单层。利用表面等离子体共振技术观察了在单层界面上互补碱基对的形成。采用简单的浇铸法制备了具有生物相容性的蜂窝状膜。在等离子体共振显微镜下观察了聚合物薄膜的二维形貌。

This study is cooperative research between physicists of the surface analysis and polymer chemists of thin film preparation. The purpose of this study is hierarchical structuring of the two-dimensional polymer complexes from nanometer to micrometer scale by using self-assembling and self-organization of molecules and molecular assemblies. Self-assembled monolayers of nucleobase amphiphile were preapered on gold surface. The formation of the complementary base pairing at the monolayer interface was observed by surface plasmon resonance technique. A honeycomb patterned film having bio-compatibility was prepared by the simple casting method. The two-dimensional topography of the patterned polymer thin film was observed as contrast image of the plasmon resonance microscope.
