An on-surface reaction confined within a porous molecular template
(The University of Nottingham, 2019-04-25)
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 ...
Giant moiré patterns and lattice-matched epitaxial graphene grown
(The University of Nottingham, 2018-01-01)
Lattice-matched graphene on hexagonal boron nitride is expected to lead to the formation
of a band-gap but requires the formation of highly strained material and has not hitherto
been realised. We demonstrate that aligned, ...
Ullmann coupling reactions on Ag(111) and Ag(110): substrate influence on the formation of covalently coupled products and intermediate metal-organic structures
(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 ...
Organisation and ordering of 1D porphyrin polymers synthesised by on-surface Glaser coupling
(The University of Nottingham, 2016-07-01)
One-dimensional polymer chains consisting of π-conjugated porphyrin units are formed via Glaser coupling on a Ag(111) surface. Scanning probe microscopy reveals the covalent structure of the products and their ordering. ...
Two-dimensional diffusion of excitons in a perylene diimide monolayer quenched by a fullerene heterojunction
(The University of Nottingham, 2019-05-09)
The structural and functional properties of organic heterojunctions play a vitally important role in the operation of organic devices, but their properties are difficult to measure directly due to the buried interfaces ...
Molecular quantum ring formed from a pi-conjugated macrocycle
(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 ...
Structural characterisation of molecular conformation and the incorporation of adatoms in an on-surface Ullmann-type reaction
(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 ...
Self-assembly of a strapped linear porphyrin oligomer on HOPG
(The University of Nottingham, 2021-11-03)
Polymeric structures based on porphyrin units exhibit a range of complex properties, such as nanoscale charge transport and quantum interference effects, and have the potential to act as biomimetic materials for light-harvesting ...
