Abstract
Mixing low molecular weight gelators (LMWGs) can be used to combine favourable properties of the individual components within a multifunctional gel. Such multicomponent systems are complex enough in themselves but the method of combining components is not commonly considered as something to influence self-assembly. Here, we investigate two multicomponent systems comprising of a naphthalene-based dipeptide hydrogelator and one of two modified naphthalene diimides (NDIs), one of which forms gels, and the other does not. We probe these systems, examining the structures formed and their gel properties (when preparing a solution from either a mixed powder of both components or by mixing pre-formed solutions of each component) using rheology, small angle neutron scattering (SANS) and absorbance spectroscopy. We find that by altering the method of preparation, we can either induce self-sorting or co-assembly within the fibres formed that underpin the gel network.
