«This research quite possibly marks the first time we have documented this experimental transformation from nano - sized giant tetrahedral to supramolecular lattices,» said Joe Akkara, a materials science program director from the National Science Foundation, which funded the research.

Scanning tunneling microscope (STM) imaging was used to characterize the nanoscale arrangement of the supramolecular lattices formed on graphite and graphene surfaces, which determines the periodicity and geometry of the induced potentials.

In this way, the researchers managed to demonstrate that organic supramolecular lattices are suitable to create controllable 1D periodic potentials on the surface of graphene.

Calculated differential electrical potential induced by a supramolecular lattice of MBB - 2 on graphene.

The supramolecular lattice is superimposed for clarity.

Not exact matches

Here a team of European researchers applied a supramolecular approach to form self - assembled organic molecular lattices with a controlled geometry and atomic precision on top of graphene, inducing 1D periodic potentials in the resulting organic - inorganic hybrid heterostructures.

P1 behavior was first investigated by STM at the liquid / solid interface: as an exemple, an arrangement of the molecules on HOPG presenting a quasi-square lattice (a = 2.1 nm, b = 2.2 nm, α = 94 °) self - assembled by hydrogen bonds between the pyridine unit and the methyl groups borne by the p - xylene core will be described, indicating strong intermolecular interactions between the molecules P1 leading to a supramolecular self - assembly independent of the underlying HOPG structure.
