Progress in the synthesis and exploitation of catenanes since the Millennium. by Evans, N, Beer, P

“…Catenanes - molecules consisting of interlocked macrocyclic rings - have been prepared by templation strategies for some thirty years. …”

Redox-active rotaxanes and catenanes for anion sensing by Evans, N

“…The exploitation of anion templated synthesis to allow for the construction of higher order structures (including [3]catenanes, a “handcuff” catenane and a Janus [2]rotaxane), as well as a [2]catenane system with anion controlled molecular motion is also described.…”

Anion-templated assembly of a [2]catenane. by Sambrook, MR, Beer, P, Wisner, J, Paul, R, Cowley, A

Anion induced and inhibited circumrotation of a [2]catenane. by Ng, K, Felix, V, Santos, S, Rees, N, Beer, P

“…The first example of a catenane capable of performing circumrotation via an anion switching methodology is described; of particular interest is a conformational locking mechanism which results from chloride coordination in the catenane binding cavity.…”

Unlinking chromosome catenanes in vivo by site-specific recombination. by Grainge, I, Bregu, M, Vazquez, M, Sivanathan, V, Ip, S, Sherratt, D

Halogen- and hydrogen-bonding catenanes for halide-anion recognition. by Gilday, L, Beer, P

“…The catenanes' anion recognition properties in the competitive CDCl(3)/CD(3) OD 1:1 solvent mixture revealed selectivity for the heavier halides iodide and bromide over chloride and acetate.…”

Halogen- and hydrogen-bonding catenanes for halide-anion recognition by Gilday, L, Beer, P

“…The stability of the anion-templated halogen-bonded pseudorotaxane architectures was exploited in the preparation of new halogen-bonding interlocked catenane species through a Grubbs' ring-closing metathesis (RCM) clipping methodology. …”

Topology of Xer recombination on catenanes produced by lambda integrase. by Bath, J, Sherratt, D, Colloms, S

“…This recombination introduced one additional node into the catenanes. Antiparallel sites on four-noded right-handed catenanes, the normal product of Xer recombination at psi, were not recombined efficiently. …”

Sulfate anion-templated assembly of a [2]catenane. by Huang, B, Santos, S, Felix, V, Beer, P

“…The sulfate anion's templating role in catenane formation is demonstrated for the first time; a novel bis-pyridinium nicotinamide [2]catenane is prepared in a remarkable high yield and is shown to exhibit selectivity for sulfate, the templating anion.…”

Evidence that the catenane form of CS2 hydrolase is not an artefact. by van Eldijk, M, van Leeuwen, I, Mikhailov, V, Neijenhuis, L, Harhangi, H, van Hest, J, Jetten, MS, Op den Camp, H, Robinson, C, Mecinović, J

“…CS2 hydrolase, a zinc-dependent enzyme that converts carbon disulfide to carbon dioxide and hydrogen sulfide, exists as a mixture of octameric ring and hexadecameric catenane forms in solution. A combination of size exclusion chromatography, multi-angle laser light scattering, and mass spectrometric analyses revealed that the unusual catenane structure is not an artefact, but a naturally occurring structure.…”

A halogen-bonding catenane for anion recognition and sensing. by Caballero, A, Zapata, F, White, N, Costa, P, Félix, V, Beer, P

“…The anion-templated synthesis of a halogen-bonding catenane, which recognizes chloride and bromide ions solely by halogen bonding, is described. …”
