    “…We demonstrate the first example of bidirectional reversible electronic energy transfer (REET) between the mechanically bonded components of a rotaxane. Our prototypical system was designed such that photoexcitation of a chromophore in the axle results in temporary storage of electronic energy in a quasi-isoenergetic “reservoir” chromophore in the macrocycle. …”

    “…A family of novel halogen bonding (XB) and hydrogen bonding (HB) heteroditopic [2]rotaxane host systems constructed by active metal template (AMT) methodology, were studied for their ability to cooperatively recognise lithium halide (LiX) ion‐pairs. (1)H NMR ion‐pair titration experiments in CD(3)CN:CDCl(3) solvent mixtures revealed a notable “switch‐on“ of halide anion binding in the presence of a co‐bound lithium cation, with rotaxane hosts demonstrating selectivity for LiBr over LiI. …”

    “…Here we report studies to attach polymetallic complexes to polymer beads for the first time, producing beads of around 115 microns diameter that are attached to 10(14) hybrid inorganic-organic [2]rotaxanes. The bead is then formally a [10(14)] rotaxane. …”
