Polymorphic Architectures of Graphene Quantum Dots

A systematic strategy for designing structured nanomaterials is demonstrated through self-assembly of graphene quantum dots. The approach reveals that graphene derivatives at the nanoscale assemble into various architectures of nanocrystals in a binary solution system. The shapes of the nanocrystals continue to evolve in terms of the intimate association of organic molecules with the dispersion medium, obtaining a high index faceted superlattice. This facile synthetic process provides a versatile strategy for designing particles to new structured materials systems, exploiting the crystallization of layered graphitic carbon structures within single crystals.

A versatile synthetic process for producing a highly faceted graphene quantum dots (GQDs)-based superlattice is established by precise control of the intimate association of GQDs with solvents as well as structural-guided optical properties. Pair potentials are examined using the Derjauin, Landau, Verwey, and Overbeek theory to disentangle the evolutionary polymorphism of layered graphitic carbons, from simple cubics to truncated structures.
