A novel [2]pseudorotaxane was successfully constructed by the complexation of dibenzo[24]-crown-8 (DB24C8) derivative bearing terpyridine moiety (1) with lanthanide ion (Tb3+) and fullerene-containing ammonium salt (2), exhibiting the controlled photophysical behaviors as a reversible luminescent lanthanide switch in the presence of K+ or 18-crown-6 (18C6).

A novel mechanically bonded amphiphile (MBA)-bistable [2]rotaxane H2 was designed and prepared. In both the solution and aggregated states, H2 demonstrated pH-responsive emissions due to the presence of a distance-dependent photoinduced electron transfer (PET) process. Moreover, the morphology of H2 aggregates can be tuned from nanospheres to vesicles due to the pH-controlled shuttling motion-induced
