“…This strategy has been extended recently to second-generation pseudorotaxanes in which the metal-complex photosensitizer, which can also be called a ªlight-fueledº motor, has been incorporated (Scheme 33) either into the thread [139] or into the ring [140] component. [141] The construction of these ªintegratedº pseudorotaxanes is not an easy task and so careful design is of paramount importance before embarking on sometimes time-consuming and demanding synthetic work.…”

“…Photocontrollable molecular machines based on pseudorotaxanes. [139,140] In these second-generation systems the ªlight-fueledº motor (namely, the photosensitizer) is part of the acyclic and of the macrocyclic components of [28´48] 4 Scheme 34. The shuttling of the macrocyclic component of 50 4 along its dumbbell-shaped component can be controlled [142] chemically or electrochemically in CD 3 CN at 229 K by protonating/deprotonating or oxidizing/reducing the benzidine unit.…”

“…In diesen Systemen, die man als lichtbetriebene Motoren bezeichnen könnte, wurde der als Photosensibilisator verwendete Metallkomplex entweder in die fadenförmige [139] oder in die makrocyclische Komponente [140] eingebaut (Schema 33). [ [57, 134a] Schema 33.…”

“…The first attempts aimed at exploiting photoinduced electron transfer to bring about large-amplitude controllable molecular motions involved the light-driven threading-dethreading of pseudorotaxane-type complexes [73][74][75][76][77][78]. On the basis of the experience gained with some of these model systems [76], the bistable rotaxane 3 6+ ( Figure 5) was specifically designed [79] to achieve photoinduced ring shuttling in solution.…”
