| Description | The binding interactions between the host cucurbit[7]uril (CB7) and a series of linear guests contg. 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 pseudorotaxane and rotaxane compds. were synthesized utilizing the host-guest interactions between CB7 and the surveyed guests. |
