| Abstract;Herein reported is a chiral induction and a memory effect in the assembly of the cages. We found that a chiral guest induced a 3:2 diastereomer selectivity in the organization of (P)- and (M)-cages. The (P)..LAR..RAR..(M) equilibration (racemization), being bimolecular process as revealed by a kinetic study, was supressed at low concentration. Therefore, the molecular chirality once generated in the framework was memorized at low concentration even after guest removal, showing that the asymmetric cage acted as a Chirality Memory.
