    Together with rotaxanes and borromean rings, catenanes are interlocked DNA The synthesis of DNA catenanes for applications in DNA nanotechnology often . the other would represent the “1” state of one bit of a computer memory. Olympiadane is a mechanically-interlocked molecule composed of five interlocking macrocycles that resembles the Olympic rings.

    The molecule is a linear pentacatenane or a [5]catenane. any practical use in mind, although other catenanes may have possible application to the construction of a molecular computer.
    In one such system [8] one macrocycle is an electron deficient oligo Bis-bi pyridinium ring and the other cycle is crown ether cyclophane based on para phenylene or naphthalene.

    Catenanes — molecules consisting of interlocked macrocyclic rings — have been prepared by templation strategies for some thirty years. Please enable JavaScript to access the full features of the site or access our non-JavaScript page. A limited number of rapidly interchanging conformers exist for this type of compound. Modicom and S.

    A particularly interesting property of many catenanes is the ability of the rings to rotate with respect to one another. catenanes are promising systems for the construction of artificial miniaturization will not only decrease the size and increase the power of computers.

    supramolecular assemblies can find applications as machines at the molecular level. Focus is placed on photoconductive (poly)rotaxanes and (poly)catenanes.

    ethers, are promising candidates for new photoconductivity-related applications.
    The interlocking ring is self-assembled when two more phenanthroline units with alkene arms coordinate through a copper I complex followed by a metathesis ring closing step. Back to tab navigation Fetching data from CrossRef.

    Stoddart and Vogtle have, however, obtained [n]poly- catenane structures by This technique is therefore far from being mastered in wider applications.

    There are two primary approaches to the organic synthesis of catenanes. The Journal of Organic Chemistry. Catenanes have been synthesised in two different ways: statistical synthesis and template-directed synthesis.

    An example of this approach used bis-bi pyridinium salts which form strong complexes threaded through crown ether bis para -phenylene crown Fraser; Williams, David J.

    Each noncovalent approach to catenane formation results in what can be considered different families of catenanes.

    Play media. Another family of catenanes are called pretzelanes or bridged [2]catenanes after their likeness to pretzels with a spacer linking the two macrocycles.
