Slow-exchange C3-symmetric cryptand/trispyridinium inclusion complexes containing non-linear guests: a new type of threaded structure

Slow-exchange C3-symmetric inclusion complexes were successfully prepared based on a new cryptand/trispyridinium recognition motif as confirmed by proton NMR spectroscopy, electrospray ionization mass spectrometry, and molecular modeling. These inclusion complexes are the first examples of a new type of threaded structure with non-linear guests.
