Title

Molecular self-assembly in hydrogen-bonding rich non-aqueous solvents

Abstract

Hydrogen-bonding is a key fundamental parameter in self-assembly of amphiphiles, driving aggregation via the hydrophobic effect. Hydrogen-bonding rich non-aqueous solvents are of interest as they are analogous to water, the archetypal solvent with a dense hydrogen bonded network. Non-aqueous solvents can provide advantages, such as high boiling points and excellent solvency for organic molecules. However, self-assembly in H-bonding rich non-aqueous solvents is not well understood. Here, in collaboration with the GSK Oral Health Division, we propose a small-angle neutron scattering study (SANS) of self-assembled structures formed by surfactants in several H-bonding rich non-aqueous solvents, including ethylene glycol, propane-1,3-diol and propylene glycol, which vary in the H-bonding number and density. We will vary surfactant architecture (comparing anionic, cationic and zwitterionic surfactants), as well as the surfactant concentration. We also propose to investigate the temperature effect on these systems, as it has been shown in preliminary studies to have a profound effect on the self-assembly mechanism.
