| Outline of Final Research Achievements |
Under the proposed research grant, a solution growth mechanism of metal-organic nanostructured arrays formed on the metal surface has been studied. Nano-scale microscopy combined with Raman spectroscopy set-up has been constructed and used to obtain simultaneously information on the nanoscale order structure and chemical composition of the arrays. Two types of organic ligands adsorbed on the gold surface were investigated. It has been found that well-defined metal-organic framework structures composed by ad-molecules and ad-atoms can be formed in the presence of hydrogen chloride. Detail analysis by both the set-up and computational chemistry revealed that the nanostructures are composed of protonated ligand molecules and a surface chloride compound which guides their self-assembly into three dimensional structures via attractive hydrogen bonding and unique interactions between gold atoms.
