Order, disorder, and metalation of tetraphenylporphyrin (2H-TPP) on Au(111)

Edmondson, Matthew Richard; Saywell, Alex; Frampton, Eleanor (The University of Nottingham, 2022-05-09)

A thermally induced order–disorder transition of tetraphenylporphyrin (2H-TPP) on Au(111) is characterised by scanning probe microscopy and X-ray photoelectron spectroscopy-based techniques. We observed that a transition ...
Ullmann coupling reactions on Ag(111) and Ag(110): substrate influence on the formation of covalently coupled products and intermediate metal-organic structures

Judd, Chris J.; Saywell, Alex (The University of Nottingham, 2017-11-09)

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 ...
Van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride

Beton, Peter (University of Nottingham, 2015-10-01)

The fluorescence of a two-dimensional supramolecular network of 5,10,15,20-tetrakis(4-carboxylphenyl)porphyrin (TCPP) adsorbed on hexagonal boron nitride (hBN) is redshifted due to, primarily, adsorbate-substrate van der ...
