A neutral redox-switchable [2]rotaxane.
A limited range of redox-active, rotaxane-based, molecular switches exist, despite numerous potential applications for them as components of nanoscale devices. We have designed and synthesised a neutral, redox-active [2]rotaxane, which incorporates an electron-deficient pyromellitic diimide (PmI)-containing ring encircling two electron-rich recognition sites in the form of dioxynaphthalene (DNP...
متن کاملTheoretical Study Of A Switchable [2]-Rotaxane
In recent years, pioneering work carried out by Sauvage, Stoddart and co-workers [1], , has focused on the development of synthetic methodologies and the characterization of catenanes and rotaxanes. Catenanes and rotaxanes are examples of interlocked molecule. Unlike classical molecular structures, they consist of two or more separate components which are mechanically connected. Catenanes consi...
متن کاملCyclodextrin-based switchable DNA condenser.
Switchable DNA condensers based on β-cyclodextrin derivates bearing cationic imidazolium moieties and hydrolysable ester linkages were synthesized, showing base-responsive or enzyme-responsive switchable DNA condensation ability under physiological conditions.
متن کاملA cyclodextrin-insulated anthracene rotaxane with enhanced fluorescence and photostability.
A beta-cyclodextrin anthracene rotaxane was synthesized and found to be significantly more resistant to fluorescence quenching and photobleaching than the uninsulated anthracene derivative.
متن کاملSemi - Empirical Study of a pH - Switchable [ 2 ] Rotaxane
Semi-empirical (AM1) electronic structure calculations are reported on a pH-switchable [2] rotaxane whose synthesis was reported in [Angew. Chem. Int. Ed., 36 (1997) 1904]. The [2] rotaxane possesses two cationic binding sites, with different affinities toward dibenzo [24] crown-8 (the ring component of the [2] rotaxane) depending upon the pH of the system. The computational results capture thi...
