Three [2]rotaxanes (4, 7 and 12) and one [3]rotaxane (8) were synthesized based on the dibenzo-30-crown-10/viologen binding motif. To the best of our knowledge, these are the first rotaxanes formed from dibenzo-30-crown-10 and viologens. The rotaxanes were all characterized by H NMR, C NMR, and HRMS. An X-ray crystal structure of one of the [2]rotaxanes (7) was obtained. This work demonstrates for the first time that dibenzo-30-crown-10 does form pseudorotaxane complexes with viologens in solution.

Supramolecular self-assembly for designing non-centrosymmetric crystals based on Keggin polyoxometallates and crown ether.

We report the synthesis of five novel crystals [(4-BrAni+)(DB[18]crown-6)]2[SMo12O402-]·2CH3CN (1), [(4-BrAni+)(B[18]crown-6)]2[SMo12O402-]·CH3CN (2), [(4-BrAni+)(B[18]crown-6)]3[PMo12O402-]·2CH3CN...

Length and flexibility of molecular translocator of macrocycle matters for the synthesis of improbable 2rotaxanes.

We report on the use of molecular translocators aimed to capture a dibenzo-24-crown-8 (DB24C8), then to release it onto targeted molecular axles, to afford after removal of the translocator, [2]rotaxa...

Hybrid organic-inorganic rotaxanes, including a hetero-hybrid 3rotaxane featuring two distinct heterometallic rings and a molecular shuttle.

[2] and [3] hybrid rotaxanes are reported based on {Ti7M} rings (where M = a trivalent metal such as FeIII or GaIII}. NMR studies show that [2]rotaxanes can act as molecular shuttles, while EPR studie...

Driving Quick and Large Amplitude Contraction of Viologen-Incorporated Poly-L-Lysine based Hydrogel by Reduction.

A glutaraldehyde-crosslinked poly-L-lysine-based hydrogel with pendant viologens was synthesized with various [viologen unit]/[Lys unit] ratios. The hydrogel with the ratio of 25% was extensively char...

Restricting shuttling in bis(imidazolium)…pillar5arene rotaxanes using metal coordination.

Metal coordination to a series of bis (imidazolium)…pillar[5]arene [2]rotaxanes through the formation of metal-carbene bonds facilitates a new strategy to restrict the shuttling motion in [2]rotaxan...

Medical and Biotech [MESH] Definitions

Complex compounds in which a dumbbell shaped molecule is encircled by a macrocycle. They are named after rota (wheel) and axis (axle). Notation with a prefix is used to indicate the number of interlocked components. They have potential use in NANOTECHNOLOGY. Rotaxanes have been made with CYCLODEXTRINS and CYCLIC ETHERS.

Compounds based on a 7-membered heterocyclic ring including an oxygen. They can be considered a medium ring ether. A natural source is the MONTANOA plant genus. Some dibenzo-dioxepins, called depsidones, are found in GARCINIA plants.

Macrocyclic compounds analogous to CROWN ETHERS but which lack any OXYGEN atoms.

In utero measurement corresponding to the sitting height (crown to rump) of the fetus. Length is considered a more accurate criterion of the age of the fetus than is the weight. The average crown-rump length of the fetus at term is 36 cm. (From Williams Obstetrics, 18th ed, p91)

1,1'-Bis(phenylmethyl)4,4'-bipyridinium dichloride. Oxidation-reduction indicator.
