Outline of Final Research Achievements

Present study has established successfully the Single Particle Triggered Linear Polymerization (STLiP) method which allows us to fabricate uniform 1D nanostructures via polymerization/crosslinking reactions confined into a nm-scaled cylindrical area of solid state ubiquitous organic molecules. The dimensions of the obtained nanostructures were perfectly under control in their sizes, orientation, and number density. Standing forms of the nanowires with extremely high aspect ratio exceeding ~100 on a substrate had been unexplored by the conventional nano-fabrication methods. Achieving the standing form of organic nanowires in collaborative works of KU, IUAC, GSI, and QST has been successfully implemented by 1) functional surfaces filled with extraordinary high aspect/density of the oriented nanowires, 2) nanomedicines as well as sensing platforms reflecting its gigantic surface area, and 3) Electrical current control along the 1D nanowires.

Academic Significance and Societal Importance of the Research Achievements

ナノ構造形成におけるさまざまな手法が展開され,特に電子素子形成に決定的な役割を果たす中,その微細構造化はようやく2次元の束縛を離れ,3次元構造へと展開しようとしている.数nm領域の最先端材料微細化において,ボトムアップ型規則性均一ナノ構造形成の主流であるリソグラフィー技術が決して到達できなかった,アスペクト比:数10をはるかに凌駕する100以上に達する直立型ナノ構造を,本研究のSTLiP法がきわめて簡便に達成できることを示した.ごくありふれた有機分子性物質を選択し,その機能を生かしたナノ材料化が可能であることは,従前のナノ材料研究における学術的・社会的常識を覆す発見である.
