Poly(vinyl pyrrolidone)-Sodium bis(2-ethylhexyl)sulfosuccinate Complex as Probe to Study the Inclusion Complex of b-Cyclodextrin with Sodium bis(2-ethylhexyl)sulfosuccinate in Aqueous Solution
Asian Journal of Chemistry,

Abstract
Poly(vinyl pyrrolidone) (PVP)-sodium bis(2-ethylhexyl) sulfosuccinate (AOT) complex has been used as a viscosity probe to study the inclusion complexation between b-cyclodextrin (b-CD) and AOT. Viscosity measurements show that the inclusion complexation between b-cyclodextrin and AOT may cause the AOT molecules being stripped off the PVP chains, resulting in the decrease of the solution viscosity due to the decaease of electrostatic repulsion between polymer-bound AOT micelles. The viscosity minimum at Cb-CD/CAOT = 1 indicate the molecular ratio of host molecule to guest molecule is 1:1 in the b-CD/AOT inclusion complex.
