Summary
This inter-disciplinary project, based across the Schools of Physics and Chemistry at the University of Leeds, aims to exploit the nano structuring of molecular assemblies on surfaces in order to create novel functional 2D surfaces. Nanometre sized building blocks formed from organic molecules will be synthesised in the group of Dr Thomas Chamberlain (https://chamberlainresearchgroup.com/) and then used to create 2D molecular arrays on a range of prototypical surfaces in Dr Adam Sweetman’s group (https://nca.fm/).
You will work with both groups to investigate how both the nature of the component building blocks, and the overarching supramolecular structure of the assembly, affect the properties of these new surfaces. This will be done using a range of cutting-edge characterisation techniques allowing us to understand the properties of the new materials both on the ensemble, and single molecule, level.

In this project we will investigate the development of organic molecular building blocks to create self-assembled 2D nanostructured materials, with a focus on creating novel hybrid materials aimed at tackling a number of core scientific challenges, including molecular detection and catalysis. You will identify suitable methodologies for synthesising thin molecular films, including ambient solution based deposition and ultra-high-vacuum (UHV) techniques such as molecular beam epitaxy. You will then use advanced surface characterisation techniques including scanning tunnelling microscopy (STM) and noncontact atomic force microscopy (NC-AFM) to determine the structure and properties of the assembled molecular films in real space with sub-molecular resolution. By probing these nanomaterials at the single molecule level, we will aim to link the atomic scale properties of the components to the bulk (ensemble) properties of the film itself in order to improve our fundamental understanding of how to design novel nanostructured materials from the bottom up. This project will target the development of functional building blocks and exploit the self-assembly of these materials on surfaces for the fabrication of novel 2D nanomaterials. As the principle component of such nanomaterials will be both renewable and almost infinitely available, i.e. carbon, this represents a sustainable route to novel nanomaterials. |
