Lyotropic chromonic liquid crystals (LCLCs) are a class of lyotropic liquid crystals (LLCs), which are generally composed of amphiphilic molecules. In aqueous solutions, chromonic liquid crystals form rod-like supramolecular assemblies driven by π-π stacking of aromatic rings and nanophase separation of hydrophobic and hydrophilic parts. Such chromonic aggregates tend to orient in one direction and form a liquid crystal order depending on concentration and temperature. In this study, chromonic liquid crystals with a negative charge were introduced into a polymer gel with a positive charge. The temperature dependence of the stacking order was evaluated under a polymer-mediated aqueous environment.
