We report here that a novel class of physical gels, which are based on self-organization of a gelling agent, exhibits thermoreversible two gel states derived from liquid-crystalline and isotropic states. We focus on trans-1,2-bis(acylamino)cyclohexane derivatives for the gelling agent. Room-temperature nematic liquid crystals, 4-pentyl-4'-cyanobiphenyl (5CB) and E7 have been used as anisotropic solvents. These molecules have been successfully gelled through the self-aggregation of the gelling agents. This aggregation is driven by the formation of H bonds between the amide linkages. The mixtures show thermoreversible three states, liquid-crystalline gel, normal (isotropic) gel, and isotropic liquid The gels are responsive to electric fields and show electro-optic properties. These anisotropic materials would be applicable for new electro-optic materials.
