High in fiber: 1D fibrous superstructures are formed by an enantiopure phthalhydrazide‐functionalized helicene in nonpolar solvents. Trimeric disks are formed by hydrogen‐bonding interactions of phthalhydrazide units that are longitudinally interlocked for optimal packing (see picture). The resulting supramolecular assemblies exhibited large circularly polarized luminescence in solution.
