Rotaxanes with fluorocarbon blocking groups.
A novel [2]-rotaxane has been prepared in which perfluoropropyl stoppers have been utilized as electronic blocking groups. To further investigate this capability, a linear compound that was precapped with perfluoropropyl groups was also prepared. This compound did not demonstrate rotaxane formation when mixed with dibenzo-24-crown-8, providing further evidence that the perfluoropropyl groups were effective electronic stoppers for the macrocycle.
