Low molecular weight gelators (LMWG) form hydrogels via self-assembly in water under specific conditions to form long, fibrillar structures. Non-covalent forces interactions which facilitate the directional assembly include hydrogen-bonding, electrostatic interactions, π-π stacking and van der Waals interactions between the molecules drive the assembly. The fibrillar structures entangle, forming a three-dimensional network and immobilise the solvent, resulting in gel formation. This proposal focuses on the characterization of the structures formed from on mixing a novel series of dipeptide based molecules and seeks to determine whether self-sorting or intimate mixing occurs. Small-angle neutron scattering employing contrast variation is essential to address this question.
