Cyclodextrin-based catenanes and polycatenanes

In recent years, a number of interlocked molecules such as rotaxanes, catenanes, polyrotaxanes, and polycatenanes have been actively synthesized. Cyclodextrins (CDs) are representative building blocks of these interlocked molecules; however, very few reports are available on CD-based catenanes and polycatenanes. In this review article, we provide an overview of CD-based interlocked molecules and introduce examples of CD-based catenanes and polycatenanes. Finally, the perspectives of research on CD-based catenanes and polycatenanes are discussed.
