Abstract
Entering a new phase: Mesogenic stoppers (purple) at the ends of the rod section of a switchable donor-acceptor [2]rotaxane induce the formation of a smectic A liquid-crystalline (LC) phase over a wide temperature range. The bistable [2]rotaxane which contains a tetracationic cyclophane (blue), a tetrathiafulvalene unit (green), and a 1,5-dioxynaphthalene unit (red) self-assembles into a LC phase with a layer spacing of about 8 nm (see picture). (Figure Presented).
