Research Abstract	AFM探針による固体表面の物理的加工についてはすでに数多くの報告があり、申請者も半導体表面のナノメートルレベルでの加工に成功している。本研究ではこの様な単純な物理的加工ではなく、自己組織化単分子層の表面官能基を走査型プローブ顕微鏡の探針を用いて触媒化学的および電気化学的に分子変換する事によって二次元分子配列をナノメートル〜サブミクロンスケールで制御する事を目的とする。本年度の成果は以下の通りである。 1.機能性分子の合成 -NO2、-CN、-COOH、-COHおよび-C=CH2などを末端官能基としてもつアルカンチオール分子の合成を試み、そのいくつかについて成功した。 2.自己組織化単分子層の構築温度と雰囲気を制御した環境下で分子の入った有機溶液に金単結晶基板を浸漬し自己組織化単分子層を構築した。形成単分子層の構造・配向性に及ぼす単結晶基板の方位、浸漬溶液の濃度、浸漬時間および合成時(1)のアルキル鎖長の効果をSTM/反射FT-IRなどで評価した。 3.金属コートAFM探針の作製ナノ領域における反応評価には困難が予想されるため、今年度は試料との接触面積が比較的大きな探針を用いた。真空蒸着法によって探針の先に、白金、パラジウム、ニッケルなどの金属をコートした。作製された探針の先の大きさや形状は真空蒸着時の条件によって制御し、作製後電子顕微鏡(SEM)等で確認した。
