Enhancement of anion recognition exhibited by a halogen-bonding rotaxane host system. by Kilah, N, Wise, MD, Serpell, C, Thompson, A, White, N, Christensen, K, Beer, P

“…We report the first use of solution-phase halogen bonding to control and facilitate the assembly of an interlocked structure through the bromide anion-templated formation of a rotaxane based upon an iodotriazolium axle. The incorporation of a halogen atom into the rotaxane host cavity dramatically improves the anion-recognition capabilities of the interlocked receptor, giving unusual iodide selectivity in a competitive aqueous medium.…”

Halogen bonding in water results in enhanced anion recognition in acyclic and rotaxane hosts. by Langton, M, Robinson, S, Marques, I, Félix, V, Beer, P

“…Quantification of iodide binding by rotaxane hosts reveals the strong binding by the XB-rotaxane is driven exclusively by favourable enthalpic contributions arising from the halogen-bonding interactions, whereas weaker association with the HB-rotaxanes is entropically driven. …”

Anion templated formation of pseudorotaxane and rotaxane monolayers on gold from neutral components. by Zhao, L, Davis, J, Mullen, K, Chmielewski, M, Jacobs, R, Brown, A, Beer, P

“…Though the fluxional and disordered nature of ethylene glycol extended axle adlayers prohibits detectable threading on the surface, rotaxane monolayers can be generated by a preassociation of the components and templating anion in solution. …”

Polyyne [3]rotaxanes: Synthesis via dicobalt carbonyl complexes and enhanced stability by Patrick, CW, Woods, JF, Gawel, P, Otteson, CE, Thompson, AL, Claridge, TDW, Jasti, R, Anderson, HL

Preprogrammed assembly of supramolecular polymer networks via the controlled disassembly of a metastable rotaxane by Gosuke Washino, Miguel A. Soto, Siad Wolff, Mark J. MacLachlan

“…Preassembled materials are ubiquitous in our everyday life due to their readiness and functionality; an end-user simply follows instructions to assemble them and harness function. Here, metastable rotaxanes are utilized to approach preassembled materials: a multicomponent, preprogrammed system can be conveniently (via heating) transformed into colorful polymer networks at the end-user’s will.…”
