| Outline of Final Research Achievements |
The present research project is focused on the invention of new chemistry for atomically precise oxidation and alkylation of graphene, which can lead to entirely new classes of two-dimensional nanomaterials with vast tunability in chemical, electrical, and optical properties. I have investigated aqueous phase oxidation of epitaxial graphene (EG) on the Si-face of the SiC substrate using two different methods, which results oxidized EG with high concentration of chemisorbed O species. I have also developed a new chemical approaches for alkylation/arylation of EG through photochemical chlorination of graphene followed by reaction with Grignard’s reagent.
To see if the other halogenated graphene can be utilized for further modification, I have made detailed investigation of halogenations of EG on SiC and its reaction with aryl Grignard reagents.
