Summary on Grant Application Form |
Unlike many model adsorbates studied in surface science, heterocyclic molecules have a choice of how they bond to a surface. This choice arises from the bifunctionality of these molecules which, in the case of thiophene, allows it to bond via either the pi system of the aromatic ring, or the S long pair electrons. The result of thiophene having more than one bonding interaction is that it exhibits complex adsorption behaviour whereby, depending on coverage, thiophene can bond either in a flat (via the pi system) or upright (via the S lone pair) geometry. In this proposed programme, we aim to discover if simple substituent groups can be used to promote one form of bonding over another. More specifically, we intend to determine if the electronic nature of the substituent, electron donating or withdrawing, influences whether thiophene bonds in a flat lying or upright geometry. To achieve our goals we will study these systems using established ultra high vacuum (UHV) surface science techniques. This proposal offers the opportunity of applying UHV surface science techniques, which have traditionally been used to study simple diatomic and polyatomics, to investigate the adsorption behaviour of a series of relatively complex technologically relevant aromatic molecules.
