Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry (2015)
Journal Article
Whitelam, S., Tamblyn, I., Garrahan, J. P., & Beton, P. H. (2015). Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry. Physical Review Letters, 114(11), Article 115702. https://doi.org/10.1103/PhysRevLett.114.115702

© 2015 American Physical Society. We show that model molecules with particular rotational symmetries can self-assemble into network structures equivalent to rhombus tilings. This assembly happens in an emergent way, in the sense that molecules sponta... Read More about Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry.

Supramolecular nesting of cyclic polymers (2015)
Journal Article
Kondratuk, D. V., Perdigão, L. M., Esmail, A. M., O'Shea, J. N., Beton, P. H., & Anderson, H. L. (2015). Supramolecular nesting of cyclic polymers. Nature Chemistry, 7(4), 317-322. https://doi.org/10.1038/nchem.2182

Advances in template-directed synthesis make it possible to create artificial molecules with protein-like dimensions, directly from simple components. These synthetic macromolecules have a proclivity for self-organization that is reminiscent of biopo... Read More about Supramolecular nesting of cyclic polymers.

In graphene devices decorated with a layer of near-infrared colloidal PbS quantum dots (QDs), the choice of the QD capping ligands and the integrity of the QD layer have a strong influence on the doping, carrier mobility, and photoresponse. By using... Read More about Ligand-induced control of photoconductive gain and doping in a hybrid graphene-quantum dot transistor.

Adsorbate-induced curvature and stiffening of graphene (2014)
Journal Article
Svatek, S. A., Scott, O. R., Rivett, J. P., Wright, K., Baldoni, M., Bichoutskaia, E., Taniguchi, T., Watanabe, K., Marsden, A. J., Wilson, N. R., & Beton, P. H. (2015). Adsorbate-induced curvature and stiffening of graphene. Nano Letters, 15(1), https://doi.org/10.1021/nl503308c

The adsorption of the alkane tetratetracontane (TTC, C44H90) on graphene induces the formation of a curved surface stabilized by a gain in adsorption energy. This effect arises from a curvature-dependent variation of a moiré pattern due to the mismat... Read More about Adsorbate-induced curvature and stiffening of graphene.

Vernier templating exploits a mismatch between the number of binding sites in a template and a reactant to direct the formation of a product that is large enough to bind several template units. Here, we present a detailed study of the Vernier-templat... Read More about Vernier-Templated Synthesis, Crystal Structure, and Supramolecular Chemistry of a 12-Porphyrin Nanoring.
