A Graphene quantum dots have received great attention for a potential role in the development of unique optoelectronic materials. In the development of optoelectronic devices, the preparation of GQDs that are controlled with their size and dimensions and are un-oxidized at the sp² surfaces is needed. We developed GQDs functionalized with bulky dendritic wedges at the GQD periphery. The single-layered and size-regulated structures of the dendronized GQDs were revealed by atomic force microscopy. The edge-functionalization of the GQDs gave rise to uncommon white light emission.

In this presentation, I will describe the synthesis and characterization of newly developed graphene quantum dots, and the unique photochemical features.
