A review of heteroditopic interlocked molecules and their application as receptors for simple inorganic ion pair species. The details the design recognition properties rotaxane catenane receptors, well highlighting some experimental challenges; hence, it provides insight into possible future avenues research in this youthful field.

Ion-pairing is reported to improve the lipophilicity and subsequently the transport rate of polar drugs across lipid membranes. Lipophilisation of ionic drugs with high aqueous solubilities by ion-pair formation with appropriate counter-ion have proven to be promising for several applications. The aim of this review is to present the usefulness of ion-pair for improving the poor bioavailability...

We propose a scheme for generating vibrational pair coherent states of the motion of an ion in a two-dimensional trap. In our scheme, the trapped ion is excited bichromatically by three laser beams along different directions in the X-Y plane of the ion trap. We show that if the initial vibrational state is given by a two-mode Fock state, the final steady state, indicated by the extinction of th...
