| Outline of Final Research Achievements |
Anodic porous alumina, which is formed by anodization of Al in an acidic electrolyte, has been attracted increasing interest as a key material for the fabrication of various functional devices. In the preset study, we investigated the preparation of ordered anodic porous alumina with holes on a single nanometer scale and its application for functional optical devices. As a result of this study, ordered anodic porous alumina with a hole diameter of less than 10 nm were successfully obtained. In addition, obtained anodic porous alumina could be used as a template for the preparation of functional optical devices. The obtained optical device was effective as a micro-photochemical reaction field based on localized light.

| Academic Significance and Societal Importance of the Research Achievements |
アノード酸化ポーラスアルミナは，幾何学形状の制御が容易であり，板状試料として得やすい等の特徴を有しているが，一方で，細孔径，細孔周期が他のナノ構造材料に比べ大きいという課題を有しており，これが応用範囲の拡大の障害となっていた．細孔構造の微細化の実現により，ポーラスアルミナの応用分野を広げる上で，大きなインパクトをもたらすものと考えられる．また，シングルｎｍポーラス構造にもとづく精密テンプレート合成手法の確立，それに基盤を置く電子・光が微小空間に局在化した光機能デバイスの作製は，人工的なリソグラフィー手法を用いることなく新規な機能デバイスの構築を可能にするという点でも意義深い．
