Molecular quantum ring formed from a pi-conjugated macrocycle
Judd, Chris J.; Saywell, Alex (The University of Nottingham, 2020-10-14)The electronic structure of a molecular quantum ring (stacks of 40-unit cyclic porphyrin polymers) is characterised via scanning tunnelling microscopy and scanning tunnelling spectroscopy. Our measurements access the ... -
On-Surface Synthesis within a Porphyrin Nanoring Template
Judd, Chris J.; Saywell, Alex (The University of Nottingham, 2019-06-28)On-surface synthesis provides a route for the production of 1D and 2D covalently bonded polymeric structures. Such reactions are confined to the surface of a substrate and the catalytic properties of the substrate are often ... -
Structural characterisation of molecular conformation and the incorporation of adatoms in an on-surface Ullmann-type reaction
Judd, Chris J.; Saywell, Alex (The University of Nottingham, 2020-11-03)The on-surface synthesis of covalently bonded materials differs from solution-phase synthesis in several respects. The transition from a three-dimensional reaction volume to quasi two-dimensional confinement, as is the ... -
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 ...
