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 ... -
Supramolecular heterostructures formed by sequential epitaxial deposition of two-dimensional hydrogen-bonded arrays
(The University of Nottingham, 2017-05-16)Supramolecular heterostructures are formed by growing sequential layers of bi- and mono-component two-dimensional molecular arrays stabilized by hydrogen bonding. The heterostructures are formed on hexagonal boron nitride ... -
Supramolecular networks stabilise and functionalise black phosphorus
(The University of Nottingham, 2017-12-15)The limited stability of the surface of black phosphorus (BP) under atmospheric conditions is a significant constraint on the exploitation of this layered material and its few layer analogue, phosphorene, as an optoelectronic ... -
Surface-directed modulation of supramolecular gel properties
(University of Nottingham, 2016-08-02)Supramolecular materials are widely studied and used for a variety of applications; in most applications, these materials are in contact with surfaces of other materials. Whilst much focus has been placed on elucidating ... -
Triplet excitation and electroluminescence from a supramolecular monolayer embedded in a boron nitride tunnel barrier
(The University of Nottingham, 2019-12-10)We show that ordered monolayers of organic molecules stabilized by hydrogen bonding on the surface of exfoliated few-layer hexagonal boron nitride (hBN) flakes may be incorporated into van der Waals heterostructures with ... -
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 ... -
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 ... -
Ultra-high resolution imaging of thin films and single strands of polythiophene using atomic force microscopy
(The University of Nottingham, 2019-04-05)Images and related analysis relevant to this research publication.
