Abstract
Cyclodextrins have been used as a cyclic component in the construction of supramolecular architectures. Recently they have been studied as a component in the construction of rotaxanes and catenanes. A cyclodextrin ring can translocate in some rotaxane and catenane structures. Therefore, much attention has been given to cyclodextrins as a component of molecular shuttles, motors, and machines. Attempts to design and synthesize molecular-level machines using cyclodextrins as a cyclic component are described.

Molecular Catenanes, Rotaxanes and Knots

TL;DR: In this paper, the mathematical characterization of these molecular structures and the prediction of their existence are presented. But, as described in many examples in this book, the parts of a molecule cannot split if the rings are interlocked.

Stimulated Anoxic Biodegradation of Aromatic Hydrocarbons Using Fe(III) Ligands

TL;DR: It is reported that adding organic ligands that bind to Fe(III) dramatically increases its bioavailability, and that in the presence of these ligands, rates of degradation of aromatic hydrocarbons in anoxic aquifer sediments are comparable to those in oxic sediments.
