Supramolecular control of single-crystal-to-single-crystal transformation through selective guest exchange. | LitMetric

Supramolecular control of single-crystal-to-single-crystal transformation through selective guest exchange.

Chemistry

Dipartimento di Chimica Generale ed Inorganica, Chimica Analitica, Università degli Studi di Parma, Viale delle Scienze 17/a, 43124 Parma, Italy.

Published: March 2011

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.
