Cyclodextrins have been used as a cyclic component in the construction of supramolecular architectures, such as rotaxanes and catenanes.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.read more

para-Bridged symmetrical pillar[5]arenes: their Lewis acid catalyzed synthesis and host-guest property.
TL;DR: Condensation of 1,4-dimethoxybenzene with paraformaldehyde in the presence of BF3.O(C2H5)2 gave novel para-bridged pentacyclic pillar DMB (DMpillar[5]arene), which formed 1:1 host-guest complexes with dialkyl viologen and alkyl pyridinium derivatives.

The molecular necklace: a rotaxane containing many threaded α-cyclodextrins
TL;DR: In this paper, the preconditioned skeleton of a cyclodextrin-polyethylene glycol (PEG) complex was constructed by capping the chain with bulky end groups.

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.

Synthesis of a tubular polymer from threaded cyclodextrins
TL;DR: In this article, the crosslinking of adjacent cyclodextrins in apolyrotaxane to create a molecular tube has been reported, with diameters of 0.45 nm, 0.7 nm and 0.85 nm.

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.
