The assembly of single-layer graphene oxide and graphene using molecular templates

Charged molecular templates were created to direct the placement of single-layer graphite oxide (GO) sheets. The distribution of the GO sheets depended on the surface functionalization, background passivation, pH, and deposition time. Electrostatic attraction guides the templating of the GO sheets and, consequently, templating could be modulated by adjusting the pH of the deposition solution. In contrast to CNT immobilization, we find that the GO sheets do not adhere to the bare Au surface.
