项目摘要

We aimed to characterize phenomena associated with irradiation onto interfaces mainly between solids and solutions, and applied them to functional devices with the theme of "Generating Micropatterns of Functional Conducting Polymers with Area-Selective Photoelectrolysis".1) Development of area-selective photoelectrolysis.Readtions take place at semiconductor electrode surfaces insolution when the sufaces were illuminated. We can thus make polymer patterns area-selectively using, for instance, pyrrole as a monomer material. We named this as "area-selective photoelectropolymerization", and have succeeded to make fine patterns of conducting polypyrrole films on several semicondutors.2) Functionalizing conducting polymer films with an incorporating reaction.We developed a method to incorporate functional molecules into polyphrrole films during photoelectrolysis, and showed an application to electrochromic devices.3) Development of an optical waveguide method to understand phtoelectrolysis.We developed an optical waveguide method to understand phtoelectrolysis reactions in detail. this method enables us to enlarge optical changes associated with surface reactions by several orders of magnitude. We characterized the basis of this method and applied it to relatively simple systems.4) Characterizing interfaces with a laser-induced photopotentialmethod.A laser-induced photopotential mehtod was developed and applied to various interfaces. We found that this method is very useful to obtain band bnding at the interfaces and to estimate leakage currents.

我们的目标是表征与主要在固体和溶液之间的界面上的照射相关的现象，并将其应用于以“通过区域选择性光电解生成功能性导电聚合物的微图案”为主题的功能器件。1) 区域选择性光电解的发展。阅读当表面被照射时，在溶液中的半导体电极表面处发生。因此，我们可以使用例如吡咯作为单体材料来选择性地制作聚合物图案。我们将其命名为“区域选择性光电聚合”，并成功在多个半导体上制作了导电聚吡咯薄膜的精细图案。2）通过掺入反应对导电聚合物薄膜进行功能化。我们开发了一种在光电解过程中将功能分子掺入聚吡咯薄膜的方法，并展示了在电致变色器件中的应用。3）开发了一种光波导方法来了解光电解。我们开发了一种光波导方法来详细了解光电解反应。这种方法使我们能够将与表面反应相关的光学变化放大几个数量级。我们表征了该方法的基础并将其应用于相对简单的系统。4）用激光诱导光势方法表征界面。开发了激光诱导光势方法并将其应用于各种界面。我们发现这种方法对于获得界面处的能带结合和估计漏电流非常有用。
