文摘

Simply by introducing steric side chains, the shape-persistent cyclo[6]aramides were found to exhibit nonaggregational behavior and strong association (3 脳 10⁴ M^鈥?) ability in acetone for binding secondary ammonium salt. The complexation can be switched in an on-and-off fashion using AgPF₆ and TBACl, contrasting sharply with their corresponding acyclic pentamer and demonstrating the macrocyclic effect.
