Synthesis of an Organic-soluble pi-Conjugated [1]Rotaxane
An organic-soluble pi-conjugated [1]rotaxane has been synthesized by intramolecular self-inclusion of a lipophilic per-methylated alpha-cyclodextrin bearing a rigid pi-conjugated system as a guest moiety. End-capping has been achieved successfully by connecting an aniline moiety without using bulky stoppers. The structure of the [1]rotaxane was determined by 2D NMR spectroscopy.
