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.

这项研究是表面分析物理学家和薄膜制备高分子化学家之间的合作研究。本研究的目的是通过利用分子和分子组装体的自组装和自组织来分层结构从纳米到微米尺度的二维聚合物复合物。在金表面制备了核碱基两亲物的自组装单分子层。通过表面等离子体共振技术观察单层界面互补碱基配对的形成。采用简单流延法制备了具有生物相容性的蜂窝图案薄膜。通过等离子体共振显微镜的对比图像观察图案化聚合物薄膜的二维形貌。
