An Hermaphrodite [2]Rotaxane:  Preparation and Analysis of Structure

Abstract

[structure: see text]. The pictured rotaxane is assembled in water by capping a substituted cyclodextrin composed of the wheel and axle components. The unusual dimeric structure of the rotaxane reflects the thermodynamics of the assembly process. In N,N-dimethylformamide, the corresponding monomer is the predominant product.
