摘要
[GRAPHICS] A rotaxane-like complex, based on a dumbbell-shaped component containing an NH2+ recognition site for a [25]crown-8 ring component and a slippage stopper in the form of a p(tert-butyl)phenyl group, has been synthesized by a "threading-followed-by-stoppering" approach. The half-life for dissociation of this complex, which is very sensitive to its environment, can be varied from minutes to months by changing the temperature and the polarity of the solvent.
