In this presentation, our recent research achievements associated to nanoscale molecular scale assembly of B- or N-doped graphitic carbon nanomaterials will be presented. In our approach, graphitic carbons can be efficiently processed into various three-dimensional structures via self-assembly principles. For instance, aqueous dispersion of graphene oxide shows liquid crystalline phase, whose spontaneous molecular ordering is useful for display or fiber spinning. In addition, the substitutional doping of graphitic carbon with B- or N- was achieved via pre- or post-synthetic treatment. The resultant chemically modified graphitic carbons with tunable workfunction and remarkably enhanced surface activity could be employed for organic solar cells, and nanocomposites for improved functionalities and performances. |
