客体可切换晶体：四膦酸空穴和 Tiiii[H,CH(3),Ph] 作为主体的固态客体交换促进单晶到单晶的转变（见图）。在所有三相（气、液、固）中都观察到对甲醇的强烈偏好，从而证明了预组织空腔通过协同氢键和 C-H⋅⋅⋅π 相互作用所发挥的基本作用。
Guest-switchable crystals: A solid-state guest exchange of the tetraphosphonate cavitand Tiiii[H,CH(3),Ph] as host promotes single-crystal-to-single-crystal transformations (see graphic). The strong preference for methanol over water is observed in all three phases (gas, liquid, solid), thus demonstrating the fundamental role played by the preorganized cavity through synergistic H-bonds and C-H⋅⋅⋅π interactions.
