    Articles on Catenanes

    1. Construction of an interpenetrated structure of macrocycles.
      Yingjie Y Zhao, Yuliang Y Li, ... Huibiao H Liu

      Chem Commun (London) 46(31):5698-700 (2010) PMID 20593099

      The construction of an interpenetrated structure of macrocycles by a CuAAC "click" reaction was achieved and the binding selectivity of indolocarbazole for a chloride anion was enhanced upon catenanation.
    2. A bistable poly[2]catenane forms nanosuperstructures.
      Mark A MA Olson, Adam B AB Braunschweig, ... J Fraser JF Stoddart

      Angew Chem Int Ed Engl 48(10):1792-7 (2009) PMID 19180620

      Side-chain poly[2]catenanes at the click of a switch! A bistable side-chain poly[2]catenane has been synthesized and found to form hierarchical self-assembled hollow superstructures of nanoscale dimensions in solution. Molecular electromechanical switching (see picture) of the material is demonstrat...
    3. A flavin-based [2]catenane.
      Stuart T ST Caldwell, Graeme G Cooke, ... Vincent M VM Rotello

      Chem Commun (London) (2008) PMID 19030536

      We report the synthesis, solid-state and preliminary solution properties of a flavin-based [2]catenane.
    4. Dynamic combinatorial discovery of a [2]-catenane and its guest-induced conversion into a molecular square host.
      Kevin R KR West, R Fred RF Ludlow, ... Sijbren S Otto

      J Am Chem Soc 130(33):10834-5 (2008) PMID 18646752

    5. Lim15/Dmc1 enhances DNA topoisomerase II catenation activity independent of sequence homology.
      Kazuki K Iwabata and Kengo K Sakaguchi

      Chromosoma 117(3):297-302 (2008) PMID 18274769

      We reported previously that Coprinus cinereus Lim15/Dmc1 (CcLim15), a meiosis-specific recA-like protein, could specifically activate C. cinereus DNA topoisomerase II (CcTopII). In particular, it enhanced the catenation activity of CcTopII in vitro at the meiotic prophase stage (Iwabata K, Koshiyama...
    6. Palladium(II)-directed self-assembly of dynamic donor-acceptor [2]catenanes.
      Yi Y Liu, Angela A Bruneau, ... Zeper Z Abliz

      Org Lett 10(5):765-8 (2008) PMID 18247625

    7. Pi-stacking enhanced dynamic and redox-switchable self-assembly of donor-acceptor metallo-[2]catenanes from diimide derivatives and crown et...
      Gayane Koshkakaryan, Kumar Parimal, ... Yi Liu

      Chemistry 14(33):10211-8 (2008) PMID 18855953

    8. Molecular catenation via metal-directed self-assembly and pi-donor/pi-acceptor interactions: efficient one-pot synthesis, characterization, ...
      Víctor V Blanco, Marcos M Chas, ... José M JM Quintela

      J Am Chem Soc 129(45):13978-86 (2007) PMID 17956095

      Dinuclear square metallocycles 3a,b assemble spontaneously when M(en)(OTf)2 (M = Pd, Pt) and a 4,4'-bipyridinium ligand are mixed in acetonitrile. Six new [3]catenanes were prepared in good yields by thermodynamically driven self-assembly reaction of molecular squares 3a,b and pi-complementary dioxo...
    9. Conformational interconversions in [2]catenanes containing a wide rigid bis(p-benzyl)methyl spacer.
      Ronald L RL Halterman, Xingang X Pan, ... Andrew T AT Long

      J Org Chem 72(17):6454-8 (2007) PMID 17630801

      The conformational interconversions of four [2]catenanes (1-4) containing a dibenzo-34-crown-10 ether (BPP34C10) interlocked with rings containing two 4,4'-dipyridiniums tethered by 1,3-bis(ethyloxy)phenyl and bis(p-benzyl)methyl spacers have been studied by VT 1H NMR spectroscopy. Symmetrically pla...
    10. Dynamic donor-acceptor [2]catenanes.
      Ognjen S Miljanic and J Fraser Stoddart

      Proc Natl Acad Sci U S A 104(32):12966-70 (2007) PMID 17670941

      We report here their thermodynamically controlled synthesis from isolated pi-donor and pi-acceptor rings under the catalytic influence of tetra butylammonium iodide. The initial nucleophilic attack of iodide ion, which opens up the pi-acceptor ring, is followed by complexation to the pi-donor ring a...
