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.

本研究是表面分析物理学家与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体的自组装和自组织作用，实现二维聚合物复合物从纳米到微米尺度的分级结构化。在金表面制备了核碱基两亲分子自组装膜。用表面等离子体共振技术观察到了互补碱基对在单层界面的形成。通过简单的流延法制备了具有生物相容性的蜂窝状图案化膜。利用等离子体共振显微镜观察图案化聚合物薄膜的二维形貌，作为对比图像。
