Charge Localization on Imidazolium Ring upon Complexation with Cucurbit[6]uril
Original language description
In this study, we demonstrate the formation of 1:1 inclusion complexes between imidazolium guests and CB6. We describe two different binding modes between CB6 and 1-alkyl-3-methylimidazoliums depending on the length of aliphatic chains of the guests. Unusual chemical shifts for some of the guest protons were recorded in the 1H NMR spectra upon the complexation with CB6. We explain these shifts by the polarization of the guest molecules upon the formation of the complex. While positive charge is locatedon one of the nitrogen atoms in imidazolium ring due to the interaction with CB6 portal, free electron pair remains on the second nitrogen.
