A volumetric study of molecular inclusion by α-cyclodextrin

Research output: Contribution to journal › Article › peer-review

Abstract

The reaction volume (Δ v̄ c→0) associated with inclusion of 3- nitrophenol by αcyclodextrin was determined by densitometry to be -9 cm³ mol^-1 while the corresponding value for encapsulation of methyl orange by two molecules of α-cyclodextrin is +27 cm³ mol^-1. These volume changes can be interpreted in terms of displacement of solvent from the cavity of α- cyclodextrin and/or changes in solvation of the 'guest' molecule.
