Rapid and simultaneous synthesis of a hydrogen bond templated [3]rotaxane and its related [2]rotaxane molecular shuttle

摘要

The rapid preparation and spectroscopic characterisation of a hydrogen bond templated [3]rotaxane and its related [2]rotaxane is presented. VT NMR spectroscopy confirms that the [2]rotaxane acts as a molecular shuttle. DFT computational modelling provides some further insight into the non-covalent interactions present within the rotaxane species.
