Synthesis and Spectral Characterization of a Rotaxane of β-Cyclodextrin Threaded by a 4,4′-Diaminostilbene
A rotaxane, in which a stilbene moiety threads the cavity of β-cyclodextrin (β-CyD), has been synthesized. The rotaxane structure has been proved by uv-visible and induced circular dichlorism (CD) spectra.
