| Abstract: | Cucurbit5]uril and decamethylcucurbit5]uril are cyclic pentamers built from glycoluril or dimethylglycoluril respectively. Two different experimental methods have been used for the synthesis of the different 2]rotaxanes. The formed rotaxanes are characterized using 1H-NMR spectroscopy, mass spectrometry and elemental analysis. In contrast to cucurbit5]uril no 2]rotaxane could be obtained with decamethylcucurbit5]uril. |
