| Abstract: | 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. |
