A new perylene bisimide dye has been synthesized that forms highly fluorescent J‐aggregates in various organic solvents and its gelation in polar solvents like acetone and dioxane is observed (see figure), whilst anisotropic highly viscous lyotropic mesophases are created in apolar solvents such as n ‐hexane or methylcyclohexane.
