چکیده

The synthesis and conformational behavior of two cyclodextrin dimers containing aromatic bipyridine spacers is presented. The proton NMR spectra of these dimers in aqueous solution show a doubling of signals in the aromatic region due to complete or partial self-inclusion of the spacer. The degree and the strength of self-inclusion is dependent on the substitution pattern of the bipyridine unit. This unexpected difference in the self-inclusion behavior is revealed by 2D NOESY and circular dichroism spectra.

The complex [Ru(bpy)2L] , where bpy = 2,2’-bipyridine, L = 4-(phenylethynyl)-2,2’-bipyridine, was prepared in its racemic and resolved forms (and . The phenylethynyl unit on the bipyridine for the complex acts as a binding site for -cyclodextrin in water (1:1 complex, K = 3390 M) or -cyclodextrin (2:1 complex, K1 = 887 M , K2 = 8070 M ). The presence of the cyclodextrin provides partial p...

Staudinger ligation towards cyclodextrin dimers in aqueous/organic media. Synthesis, conformations and guest-encapsulation ability

β-Cyclodextrin (β-CD) dimers have been prepared using the bioorthogonal Staudinger ligation for the first time. In addition to a known linker, methyl 2-(diphenylphosphanyl)terephthalate, a doubly active linker was specifically developed that enabled connection of two β-CD units in a single step and in aqueous/organic media, under mild conditions and with good yields. A three-carbon spacer betwe...
