This Letter demonstrates the molecular design of novel self-assembled chiral cryptophanes. Mediated by square-planar Pd(II) complexes, racemic pyridyl cyclotriveratrylene derivative rac-2 self-assembles into mixtures of racemic chiral cryptophanes and meso cryptophanes (1), which interconvert with each other, and the rates are remarkably enhanced by the addition of a slight excess of rac-2. On the other hand, optically resolved P-2 or M-2 self-assembles into the chiral cryptophane as the only product.
