Space filling of permethylated β‐cyclodextrin by volatile hydrophobic and hydrophilic guests in polyethylene glycol

Abstract

The inclusion of volatile organic compounds of various classes in the permethylated β‐cyclodextrin in an oligomeric solution of polyethylene glycol was investigated by inverse gas–liquid chromatography methods and by a stereochemical approach. It was established that the “guest–host” complexation process is influenced by the geometrical structure of the guest molecules, their chirality, and entropy factors.
