This research project is concerned with nanometric investigation of polymers by means of recently developed microscopy, scanning photon microscopy. This new type microscopy enables us to observe single chains with a high resolution over the diffractive limitation of light wave, and the superior performance as an optical microscope has been applied for investigating morphology of single chains, molecular assemblies, interfaces, and monolayers of polymeric materials. So far these researches have been performed on the basis of quantities ensemble-averaged even for the molecular level discussions, but this project is devoted to develop non-averaged, non-statistic polymer science and technology from real image of individual chains. The major issues are listed below.1)Two-dimensional conformation of a single macromolecule embedded in monolayers observed by scanning photon microscopy.2)Surface adsorption, chain morphology and orientation of rigid DNA chains on a solid substrate.3)Inhomogeneous nanometric structure of interpenetrating polymer network studied by fluorescence microscopy and energy transfer kinetics.4)Two-dimensional phase separation of polymer blend monolayers.5)Development of deep UV scanning photon microscope and observation of "non-fluorescnent" polymer samples.

该研究项目涉及通过最近开发的显微镜扫描光子显微镜对聚合物的纳米研究。这种新型显微镜使我们能够在光波的衍射限制上观察具有高分辨率的单链，并且已经将出色的性能作为光学显微镜进行了研究，用于研究单链，分子组件，界面，界面和单层聚合物材料的形态。到目前为止，这些研究也是基于分子级讨论的数量合奏平均水平进行的，但是该项目致力于从单个链的真实形象中开发出非平均，非统计的聚合物科学和技术。主要问题在下面列出。1）通过扫描光子显微镜观察到的单层中嵌入的单个大分子的二维构象。2）表面吸附，链形态和刚性DNA链的方向和固体子材料上的刚性DNA链的方向。动力学4）聚合物混合单层的二维相位分离。5）深紫外线扫描光子显微镜的开发以及“非氟化物”聚合物样品的观察。
