Walking Molecules on Two-dimensional Functionalised Surfaces: Using Supramolecular Chemistry to Control Motion.

Lead Research Organisation: University of Nottingham
Department Name: Sch of Chemistry

Abstract

It has long been hypothesised that molecules can be employed as nanoscale machines. This project will develop the idea of molecules that can walk across predetermined pathways. The project requires two major components: i) The synthesis of suitable molecules for both the formation of the two-dimensional self-assembled arrays and the 'walker' molecule. This aspect of the project will be overseen by Champness who has extensive experience in the synthesis of suitable molecules. ii) The self-assembly of the target molecules on 2D materials, and characterisation by scanning probe microscopies. Saywell has extensive experience in this field and will supervise this aspect of the project.

Description Throughout this project I have investigated arrangements of a porphyrin species (Tetraphenyl porphyrin - TPP) on a gold substrate. Porphyrins are a class of molecules which exhibit a range of physical properties and have the potential to be incorporated as components within molecular electronics or to act as catalytically active species (particularly when the porphyrin utilised contains a single metal adatom at it's core). This work has shown how arrays of porphyrins may be stabilised on a supporting substrate (with ordered and quasi-ordered states being controlled by substrate temperature) and that Au porphyrins can be produced via an on-surface synthesis strategy.
Exploitation Route This work could be taken forward and continued by other surface science groups using a range of different porphyrin molecules to further investigate their properties and possible uses in catalysis.
