On-surface chemical reactions characterised by ultra-high resolution scanning probe microscopy (2020)
Journal Article
Sweetman, A., Champness, N. R., & Saywell, A. (2020). On-surface chemical reactions characterised by ultra-high resolution scanning probe microscopy. Chemical Society Reviews, 49(13), 4189-4202. https://doi.org/10.1039/d0cs00166j

In the last decade it has become possible to resolve the geometric structure of organic molecules with intramolecular resolution using high resolution scanning probe microscopy (SPM), and specifically using the subset of SPM known as noncontact atomi...

An On-Surface Reaction Confined within a Porous Molecular Template (2017)
Journal Article
Judd, C. J., Champness, N. R., & Saywell, A. (2018). An On-Surface Reaction Confined within a Porous Molecular Template. Chemistry - A European Journal, 24(1), 56-61. https://doi.org/10.1002/chem.201704693

On-surface reactions based on metal-catalysed Ullmann coupling have been successfully employed to synthesise a wide variety of covalently coupled structures. Substrate chemistry and topology are both known to effect the progression of an on-surface r... Read More about An On-Surface Reaction Confined within a Porous Molecular Template.

Ullmann coupling reactions on Ag(111) and Ag(110); substrate influence on the formation of covalently coupled products and intermediate metal-organic structures Metal-Organic Structures (2017)
Journal Article
Judd, C. J., Haddow, S. L., Champness, N. R., & Saywell, A. (in press). Ullmann coupling reactions on Ag(111) and Ag(110); substrate influence on the formation of covalently coupled products and intermediate metal-organic structures Metal-Organic Structures. Scientific Reports, 7(14541), https://doi.org/10.1038/s41598-017-13315-1

On-surface reactions based on Ullmann coupling are known to proceed on coinage-metal substrates (e.g. Au, Ag, Cu), with the chemistry of the surface strongly influencing the reaction progression. In addition, the topography of the surface may be expe...

Physisorption controls the conformation and density of states of an adsorbed porphyrin (2015)
Journal Article
Jarvis, S. P., Taylor, S., Baran, J. D., Thompson, D., Saywell, A., Mangham, B., Champness, N. R., Larsson, J. A., & Moriarty, P. (2015). Physisorption controls the conformation and density of states of an adsorbed porphyrin. Journal of Physical Chemistry C, 119(50), 27982-27994. https://doi.org/10.1021/acs.jpcc.5b08350

Conformational changes caused by adsorption can dramatically affect a molecule’s properties. Despite extensive study, however, the exact mechanisms underpinning conformational switching are often unclear. Here we show that the conformation of a proto...

Self-assembled aggregates formed by single-molecule magnets on a gold surface (2010)
Journal Article
Saywell, A., Magnano, G., Satterley, C. J., Perdigão, L. M., Britton, A. J., Taleb, N., Del Carmen Giménez-López, M., Champness, N. R., O'Shea, J. N., & Beton, P. H. (2010). Self-assembled aggregates formed by single-molecule magnets on a gold surface. Nature Communications, 1(6), Article 75. https://doi.org/10.1038/ncomms1075

The spontaneous ordering of molecules into two-dimensional self-assembled arrays is commonly stabilized by directional intermolecular interactions that may be promoted by the addition of specific chemical side groups to a molecule. In this paper, we... Read More about Self-assembled aggregates formed by single-molecule magnets on a gold surface.
