Summary on Grant Application Form
The adsorption of complex molecules in which intermolecular bonding between species is likely to dominate over substrate - adsorbate interactions will be studied with STM, XPS, HREELS and LEED with the aim of developing 2-dimensional supramolecular structures. A library of potential compounds (none of which have been studied at surfaces previously) has been identified in which a range of functional groups can be introduced in different geometric positions around the molecule. In this wa hydrogen bonding will be exploited to direct the growth of the supramolecular structures. The project, which will initially involve the Ag(l 10) and Si(100) surfaces, will provide an insight into the effectiveness of the bonding between different classes of functional groups at directing the growth of surface structures and explore the relationship between the arrangement of the functional groups around the central molecular motif and the resulting 2-dimensional supramolecular structures. The adsorption o metals on top of the supramolecular structures will be studied to explore the extent to which molecular adsorbates can direct the growth of metal clusters at surfaces. The ultimate aim of this part of the project is to determine whether defects in 2-dimensional supramolecular structures can act as crystallisation points for an adsorbing metal and hence the possibility of using such structures to generate large scale and well defined arrays of nanosized particles.
