Аннотация:Dibetaines of unsaturated viologen analogues that form supramolecular complexes with cucurbit[7]uril were synthesized. The pseudorotaxane structure and stability of the complexes were established by UV/Vis and H-1 NMR spectroscopy and by X-ray diffraction analysis. Complexes of this structure are prototypes of a light-controlled molecular machine. (c) 2011 Elsevier B.V. All rights reserved.
