Summary

A research team has designed and synthesized a molecular cage with an internal cavity by connecting two curved π-conjugated molecules face-to-face at three points. The cage takes up a range of π-conjugated guest molecules through three orifices in its sides and sandwiches them between two π-conjugated panels. Guests small enough to pass through the orifices can enter and leave reversibly, and bind more strongly as their shapes better match the cavity.
