A microcantilever, coated with a monolayer of redox-controllable, bistable [3]rotaxane molecules (artificial molecular muscles), undergoes reversible deflections when subjected to alternating oxidizing and reducing electrochemical potentials. The microcantilever devices were prepared by precoating one surface with a gold film and allowing the palindromic [3]rotaxane molecules to adsorb selectiv...
The Cover Feature illustrates the acylation reaction of cyclodextrin (CD)-based [3]rotaxane. In this system, one [3]rotaxane has 36 hydroxyl groups on two CD units, and excess methacryl anhydride was added, as shown background. However, approximately only unit (highlighted by yellow color) introduced to ring when condition properly designed, probably owing steric hindrance. As a result, product...
Exceptionally strong halogen bonding (XB) donor-chloride interactions are exploited for the chloride anion template synthesis of neutral XB [2]rotaxane host systems which contain perfluoroaryl-functionalised axle components, including a remarkably potent novel 4,6-dinitro-1,3-bis-iodotriazole motif. Halide recognition properties in aqueous-organic media, determined via extensive 1H NMR halide t...
The promiscuous encapsulation of π-electron-rich guests by the π-electron-deficient host, cyclobis(paraquat-p-phenylene) (CBPQT(4+)), involves the formation of 1:1 inclusion complexes. One of the most intensely investigated charge-transfer (CT) bands, assumed to result from inclusion of a guest molecule inside the cavity of CBPQT(4+), is an emerald-green band associated with the complexation of...
A photoresponsive rotaxane based on the photoheterolysis of an acridane unit which is at the same time a bulky end group has been developed.
A beta-cyclodextrin anthracene rotaxane was synthesized and found to be significantly more resistant to fluorescence quenching and photobleaching than the uninsulated anthracene derivative.
Microwave-assisted slipping synthesis of fluorescent squaraine rotaxane probe for bacterial imaging.
Microwave heating accelerates quantitative squaraine rotaxane formation by slipping and facilitates production of a bacterial imaging probe with zinc dipicolylamine targeting ligands.
