Outline of Final Research Achievements

In a ultrahigh vacuum chamber, hexakis(benzylthio)benzene and nickel(0) were co-deposited on a graphite surface and observed its structure using STM. The co-deposition formed a three-dimensional clusters, and sheet-like products were not observed. In the next experiment, Cu(111) surface, which is supposed to interact more strongly with molecules, was employed for the deposition of hexakis(benzylthio)benzene. Several ordered structures were observed on a whole surface by STM. The formation of clear large two-dimensional sheet-like structure has not been confirmed yet, but the ordered alignment of ligand-originated molecules and metal atoms was observed in a restricted area.
