“…Temperature-dependent complexations with CDs have been extensively studied 101,[165][166][167] due to their ability to produce supramolecular structures of desired architectures. [58][59][60][61][168][169][170][171] In general, the rate of complexation of polymer with CD increased significantly with increasing temperatures.…”

This review explores the advances in stimuli-responsive polymeric inclusion complexes, comprising of cyclodextrins, in aqueous media. Cyclodextrin complexation allows these polymeric systems to possess tailored physical properties that permit them to form novel supramolecular structures. By including and combining stimuli-responsive characteristics, these special systems can transform into various morphologies when exposed to different kinds of external stimuli. A wide variety of these stimuliresponsive polyrotaxanes and functionalized cyclodextrin polymers that possess interesting supramolecular characteristics are discussed, with specific focus on pH-, temperature-, photo-and redox-sensitive systems. These unusual polymer/cyclodextrin systems provide a basis for many useful applications, such as drug delivery, environmentally friendly coatings, personal home care products, separation processes, food processing, and microelectronics.

“…Wenz et al [27] studied the complexation of a water-soluble polyester of octanedicarboxylic acid and poly(ethylene glycol) with a-, b-and hydroxypropyl-a-CD in aqueous solutions and reported the solubility change of this polymer which they attributed to the partial coverage of the polymeric guest with CD rings. So far, there are no reports on the inclusion complex formation of methylated-b-CDs with unsaturated polyesters.…”

Summary: Cyclopentadiene (1) was incorporated as a guest into the cavity of randomly methylated‐β‐cyclodextrin (me‐β‐CD) as a host, yielding the stable, water compatible cyclopentadiene/me‐β‐CD complex (1a). We successfully attempted to use the synthesised complex in a Diels–Alder addition with a water‐soluble unsaturated polyester (2) derived from poly(ethylene glycol) and maleic anhydride. The reaction yielded a new type of polypseudorotaxane (3). Examination of the polypseudorotaxane (3) and a model inclusion complex of the starting unsaturated polyester with me‐β‐CD (2a) showed that cyclodextrins are threaded onto the main chain in both cases. The cyclohexene moiety formed after the Diels–Alder addition does not act as a stopper, a dethreading process being evidenced and discussed.The polypseudorotaxane synthesized here.imageThe polypseudorotaxane synthesized here.
