Linking [2]rotaxane wheels to create a new type of metal organic rotaxane framework.
نویسندگان
چکیده
Three new [2]rotaxanes with aromatic nitrogen donors appended to the crown ether wheel have been synthesized and used as ligands to coordinate Cd(II) ions. One of these yields a new type of 2-periodic, metal organic rotaxane framework in which the wheel rather than the axle is used to link the metal nodes.

Eliminating the need for independent counterions in the construction of metal-organic rotaxane frameworks (MORFs).
The combination of a disulfonated-dibenzo-24crown-8 ether wheel and a dicationic 1,2-bis(pyridinium)ethane axle yields a neutral [2]pseudorotaxane which in combination with neutral metallic units such as a Cu(II)benzoate paddlewheel or Cu(I)Br unit yields one-dimensional coordination polymers (linear and bent) which are the first examples of charge neutral, metal-organic rotaxane frameworks.
متن کاملTemplated conversion of a crown ether-containing macrobicycle into [2]rotaxanes.
A crown ether-containing macrobicycle was used as the wheel component in a templated synthesis of a [2]rotaxane with an acetal-containing axle. The molecular structures of the macrobicycle and the [2]rotaxane were characterized by NMR spectroscopy and X-ray crystallography. The chloride-binding ability of the macrobicycle, either free in solution or when it is part of a [2]rotaxane, is quite we...
متن کاملSynthesis and evaluation of a novel Rhodamine B pyrene [2]rotaxane as an intracellular delivery agent for doxorubicin.
A novel Rhodamine B-derivatized host [2]rotaxane, containing a dibenzyl-24-crown-8 (DB24C8) ring as the wheel and a pyrene as another fluorophore blocking group, was designed, synthesized and structurally characterized. A comparison of the (1)H NMR spectra of RhBPy [2]rotaxane with those of and DB24C8, nuclear Overhauser effect spectroscopy (NOESY), mass spectrometry and fluorescence spectrosco...
متن کاملMetal-organic frameworks with dynamic interlocked components.
The dynamics of mechanically interlocked molecules such as rotaxanes and catenanes have been studied in solution as examples of rudimentary molecular switches and machines, but in this medium, the molecules are randomly dispersed and their motion incoherent. As a strategy for achieving a higher level of molecular organization, we have constructed a metal-organic framework material using a [2]ro...
متن کاملRotaxane-type resorcinarene tetramers as histone-sensing fluorescent receptors.
Rotaxane-type receptors, which were composed of anionic cyclophane-based resorcinarene tetramers as the wheel and a 2,6-disubstituted naphthalene derivative having two fluorophore moieties, such as fluorescein and rhodamine residues, as the axle ( and , respectively), were prepared. Rotaxane-type receptors and bound histone, a small basic protein component of eukaryotic chromatins, with binding...
