Abstract

Abstract: The driving force for inclusion complexation of α-and β-CD with substituted benzene(PhX) was studied by means of step-wise regression analysis. A set of multiple regression equations was established with correlation coefficients 0.96 and 0.94 for the individual complexation of α-CD and β-CD with PhX. The lnK_a(calc.) values calculated with the aid of the regression equations were close to those determined experimentally. The inclusion complexation is dominantly driven by van der Waals force and hydrophobic interactions.

Key words: Cyclodextrin, Driving force, Inclusion, Regression, Substituted benzene
