Peter R. Ashton, Martin B
lohradskż, Douglas Philp, Neil Spencer and J. Fraser Stoddart
Both a [2]- and a [3]-rotaxane have been synthesised in good yield by slippage at 55 °C in acetonitrile of bisparaphenylene-34-crown-10 over size-complementary stoppers on a dumbbell-shaped molecule containing two 4,4
-bipyridinium recognition sites.
