title: Hierarchical organization from self-assembling disulfide macrocycles.
abstract: We report cystine-based macrocyclic compounds showing very unique self-assembling behavior. 24-membered disulfide macrocycle 3 shows a helical and tubular organization and also forms an insoluble plaque that is birefringent with congo red dye. 48-membered macrocycle 4 shows a vesicle-like assembly with capability for encapsulation, as demonstrated by rhodamine B encapsulation.
