Molecular fibers and wires in solid-state and solution self-assemblies of cyclodextrin [2]rotaxanes

Abstract

Cyclodextrin [2]rotaxanes have been prepared by coupling dimethylanilines with dicarboxylic acids using DMT-MM. in aqueous solutions of a-cyclodextrin, and the example illustrated shows unusual fluorescence emission and other spectroscopic behavior characteristic of the formation of molecular wires in solution, similar to the fibers observed in the solid state.
