Generating Micropatterns of Functional Conducting Polymers with Area-Selective Photoelectrolysis

我们的目标是描述与辐射有关的现象，主要是固体和溶液之间的界面，并将它们应用于功能器件，其主题是用区域选择性光电解法生成功能导电聚合物的微图形。1)区域选择性光电解法的发展。当半导体电极表面被照射时，读出发生在溶液中。因此，我们可以使用例如吡咯作为单体材料来选择性地制造聚合物图案。我们将其命名为“区域选择性光电聚合”，并成功地在几种半导体上制备了导电聚吡咯薄膜的精细图案。2)利用结合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结合到聚吡咯薄膜中的方法，并展示了其在电致变色器件中的应用。3)发展了一种了解光电解的光波导法。我们发展了一种光波导法来详细地了解光电解反应。这种方法使我们能够将与表面反应有关的光学变化放大几个数量级。4)用激光诱导光电势方法表征界面。发展了一种激光诱导光势方法，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带隙和估计泄漏电流是非常有用的。

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.
