| Outline of Final Research Achievements |
We tried to introduce organic functional groups into the periphery of GQD-1, which carry many reactive carbon-carbon triple bonds, by the click reaction, and investigated the effects of the substituents on the photoluminescence properties of the resulting GQDs. Furthermore, we synthesized GQDs carrying two different organic functional group through developing methods of installing different functional groups into the periphery of GQDs and the polymerization properties of GQDs were investigated. The results can be summarized into three items. 1) The solubility of GQDs was influenced significantly by the substituents at the periphery. 2) The interaction between organic base and GQD, and between organic acid and GQD caused the change of the photoluminescence properties of GQDs likely due to interaction of the base and the acid with oxygen functional groups that existed at the periphery of GQDs. 3) GQDs carrying two different functional group formed supramolecular polymers.
