The surface of an aluminum plate was treated with a combination of chemical and electrochemical processes. A chemical treatment with acetone and a successive electrochemical process created a nanoscale highly-oriented grooved structure on an aluminum surface. The distance between the oriented lines was estimated as 30-40 nm by dynamic force microscopy (DFM) measurements. The present work intended to make an organic-inorganic nanoscale pattern using this nanoscale structure. Copper phthalocyanine (CuPc) and fullerene C60, which were highly-functional molecules, were selected in fabrication of nanoscale patterning. CuPc and C60 molecules were deposited on the highly-oriented line-structure on Al. A toluene droplet containing CuPc molecules was cast on the Al plate and extended on the surface. CuPc deposition on the Al surface was made by evaporation of toluene. Cross section analysis of the DFM measurements clarified that each aligned groove was filled with CuPc molecules because the depth of the channel became shallow and in some area the row width became narrower after the CuPc deposition. X-ray photoemission spectroscopy (XPS) measurements clarified that N 1s and Cu 2p lines appeared, which also supported the CuPc deposition on the nanoscale structure creating a nanoscale organic line-pattern. The spectral profile difference of Al 2p pre- and after deposition of CuPc suggested the molecular-surface interaction. Furthermore, the authors tried to make a polyaniline nanowire along the row channel fabricated on an Al surface. A droplet of HCl solution containing aniline molecules was cast and extended on the nanoscale-structured Al plate. Successively, a droplet containing APS was put and extended on the surface in order to trigger the polymerization in the nanoscale area. The DFM and XPS measurements clarified that aniline molecules were polymerized in the channel. This work was supported by High-Tech Research Center Project aided by MEXT.
