Abstract

We have investigated the effect of an inorganic electrolyte (sodium chloride) on the aggregation behaviour and liquid crystals of Edicol Sunset Yellow. Edicol self-aggregates in aqueous solution to form single molecule stacks, which then become ordered to form nematic and hexagonal (columnar) mesophases at high concentrations. We have employed changes in the 1H nuclear magnetic resonance (NMR) chemical shifts to monitor the aggregate formation in solution. A single spectrum is observed at all concentrations because the exchange between Edicol monomers in solution and those in stacks is fast on the NMR time scale. The results show that at low Edicol concentrations (
