Kinetic control of the direction of inclusion of nitroxide radicals into cyclodextrins.
نویسندگان
چکیده
N-benzyl-tert-butyl nitroxide derivatives substituted at the aromatic ring form host-guest inclusion complexes with β-and γ-cyclodextrin. They were employed as probes to assess substituent effects on the geometry of the complex and on the kinetics of this complexation by combining EPR and (1)H NMR data.

Nanoparticles of Cyclodextrins & Their Applications in Food Technology
Cyclodextrins (CDs) are a family of cyclic oligosaccharides which are composed of α (1,4) -linked glucopyranose subunits. Thebest-characterized forms are α, β and γ CD which are consisted of six, seven and eight D-glucose units, respectively. Cyclodextrins are produced from starch by enzymatic degradation. These macrocyclic carbohydrates with polar internal cavities can form complexes with and ...

متن کاملControl of spin–spin exchange interactions in polynitroxides through inclusion within c-cyclodextrin3
Supramolecular interactions of polynitroxides with c-cyclodextrin (c-CD) were used to control intramolecular electron spin–spin exchange couplings in these stable radicals. In the absence of c-CD, the binitroxide T2 and trinitroxide T3 showed strong spin–spin coupling as evidenced by the high exchange coupling constant of J = 120 MHz for T2 in its EPR spectra. Host/guest complexes are formed up...
متن کاملDevelopment and Characterization of Paracetamol Complexes with Hydroxypropyl-?-Cyclodextrin
Paracetamol is a sparingly soluble bitter tasting drug. It is widely used as an analgesic and antipyretic. Complexation of drug with different cyclodextrins (?, ? and HP-?-CD) was attempted to improve solubility of Paracetamol. During the drug excipient interaction studies, ?, ? cyclodextrins elicited analytical interference and showed considerable absorbance at ?max (243.5 nm) of Paracetamol w...
