Abstract

original image

Hin und her: Ein [2]Rotaxan aus einem α-Cyclodextrin und einem Stilbenderivat bildet ein verriegelbares molekulares Shuttle. Die Position des Shuttle wird durch den fluoreszierenden Naphthalimid-Stopper angezeigt. Im entriegelten Zustand wird das Shuttle durch Bestrahlung bei 335 nm verschoben (zur Rückkehr dient Bestrahlung bei 280 nm). Verriegelt und entriegelt wird das Shuttle durch Zugabe von Säure bzw. Base (siehe Bild).
