Abstract

Card-pack and head-to-tail types of self-assembly are formed upon aqueous dilution of capsantholon 6′-epimers dissolved in water-miscible organic solvents. Slow transformation of head-to-tail assembly into card-pack type is observed. Induced supramolecular chirality is seen upon addition of achiral β-carotene, as judged from the increased intensity of exciton signal detected in circular dichroism spectra. © 2001 Elsevier Science Ltd.
