Self-Threading of a Poly(ethylene glycol) Chain in a Cyclodextrin-Ring: Control of the Exchange Dynamics by Chain Length
摘要:
Poly(ethylene glycol) (PEG)-substituted cyclodextrins (CDs) with different chain lengths have been synthesized. PEG-substituted CDs formed self-threading complexes in aqueous solutions, and the conformational exchange dynamics between self-threading and dethreading could be regulated by its chain length.
