Outline of Final Research Achievements

We synthesized functional redox-active Ru complexes with different number of pyrene anchors. Pyrene anchors can be absorbed to pai-conjugated carbon materials such as graphene and carbon nanotubes. The adsorption stability of the Ru complex onto nano-carbon surfaces such as graphene and single-walled carbon nanotube (SWNT) were evaluated by electrochemical measurements, which provides a fundamental guideline to design the functional molecule/carbon materials nano-composites through non-covalent interactions. Additionally, we calculated the electron transfer rate from ruthenium complex to carbon materials such as single, multi-walled carbon nanotube, and HOGP.
