Water diffusion in small peptide based supramolecular materials

Abstract: Supramolecular materials, especially supramolecular gels, have gained increasing importance in material science due to the ease of modification of these materials through chemical modification of the small organic molecules they are made up of. But whilst more and more novel gelling molecules are published, the materials characterisation is mostly neglected. We have recently investigated a hydrophobic hydrogelator by quasi-elastic neutron scattering (QENS) on LET and found that the solvent in the gel diffuses quicker than in the bulk solvent. In this proposal we would like to investigate the generality of this phenomenon by measuring QENS on two small peptide supramolecular materials, a gel based on Fmoc-diphenylalanine and nanotubes based on diphenylalanine. If the quicker diffusion is a general phenomenon, tailoring diffusion in supramolecular materials will be possible.
