selective recognition event, wherein the guest substituents are oriented to both aromatic cavity ends of 3a, as confirmed by a (1)H NMR study and X-ray crystallographic analysis. Capsule 3a showed a significant solvent effect on guest encapsulation. The association constant (K(a)) of 3a with guests in C(6)D(6) was much greater than that in CDCl(3) (450-48,000-fold). The encapsulation of guests within
