Aromatic micelles: Hydrophobic and aromatic–aromatic interactions promoted the spontaneous formation of micelle-inspired molecular capsules with large aromatic shells from bent bisanthracene amphiphiles (see picture). The micellar capsules could accommodate fluorescent-dye guests in water, and the resultant nanocomposites exhibited strong fluorescence through efficient energy transfer from the host shells to the encapsulated guests.
