Abstract
The binding interactions between the host cucurbit[7]uril (CB7) and a series of linear guests containing bis(pyridinium)-1,4-xylylene and/or 4,4′-bipyridinium residues were investigated by 1H NMR spectroscopy. CB7 was found to exhibit considerable binding selectivity for bis-(pyridinium)-1,4-xylylene over 4,4′-bipyridinium sites. New pseudo-rotaxane and rotaxane compounds were synthesized utilizing the host-guest interactions between CB7 and the surveyed guests.
