Abstract
Disclosed herein is a method for preparing large soluble graphenes. The method comprises attaching one or more hindering groups to the graphene, which can prevent face-to-face graphene stacking by reducing the effects of inter-graphene attraction. The large graphenes can absorb a wide spectrum of light from UV to near infrared, and are useful in photovoltaic devices and sensitizers in nanocrystalline solar cells.
Claims12
A composition comprising a population of graphene quantum dots, wherein a quantum dot comprises graphene, a first solubilizing group, and a first binding group, wherein the first solubilizing group is a substituted phenyl moiety, wherein the substituted phenyl moiety is directly bonded to the graphene, wherein the substituted phenyl moiety comprises a substituent attached ortho- to the graphene.
