In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Rotaxanes Based on the 1,2-Bis(pyridinio)ethane-24-Crown-8 Templating Motif, published in 2011-03-31, which mentions a compound: 217192-22-8, Name is (4-(Pyridin-4-yl)phenyl)methanol, Molecular C12H11NO, Related Products of 217192-22-8.
The supramol. interaction between 1,2-bis(pyridinio)ethane axles and 24-membered crown ether wheels provides a template for the formation of interpenetrated [2]pseudorotaxanes. The preformed [2]pseudorotaxanes can then be kinetically trapped to produce permanently interlocked [2]rotaxanes by stoppering with bulky groups that prevent the unthreading of the resulting dumbbell from the wheel. Six [2]rotaxanes were created using 24-crown-8 (24C8), dibenzo-24-crown-8 (DB24C8) and dinaphtho-24-crown-8 (DN24C8) as the wheel and two methods of stoppering; alkylation of a terminal pyridine with tert-butylbenzyl groups and esterification of a terminal benzyl alc. with p-(tert-butyl)benzoate groups. The [2]rotaxanes were characterized by 1H NMR spectroscopy, electro-spray mass spectrometry and X-ray crystallog.
