Outline of Final Research Achievements

The aim of this project is to utilize the edge of nanographene for chemical reactions such as polymer synthesis. We installed organic functional groups that carried reactive parts into the edge and tried to conduct the chemical reactions. Although chemical reactions were seemed to proceed, the complete formation of the polymer structures was not succeeded. Hence, we checked the distance between the neighboring substituents by spectroscopic methods. We installed organic functional groups that can interact with each other only when the neighboring functional groups are in close proximately. As expected, the installed organic functional groups can contact each other through non-covalent bonds, indicative of the short distance between the neighboring substituents, at least 10 angstroms. Based on this data, we are now designing new organic functional groups.
