Eintritt in eine neue Phase: Mesogene Stopper (violett) an den Achsenenden eines schaltbaren Donor-Akzeptor-[2]Rotaxans induzieren die Bildung einer smektischen A-Flüssigkristallphase, die über einen großen Temperaturbereich besteht. Das bistabile [2]Rotaxan mit einem Cyclophantetrakation (blau), einer Tetrathiafulvalen- (grün) und einer 1,5-Dioxynaphthalin-Einheit (rot) bildet eine selbstorganisierte Flüssigkristallphase mit ca. 8 nm Schichtabstand (siehe Bild).
