Self assembly inclusion of ionic liquid into hollow cylinder oligosaccharides

Abstract

Self assembly of inclusion complexes and interfaces phenomena of a surface active ionic liquid (SAIL) n-dodecyl-n, n-dimethyl-3-ammonio-1-propanesulfonate (DDAPS) as a guest insight into the favorably fitted host cavity of hollow cylinder oligosaccharides such as α- and β-cylodextrins in aqueous media, have been characterized and explored on recent research gaining far achievement outcome. The interfacial inclusion complex formation has been established as manifested by surface tension and conductance measurements. These two experimentally determined parameters have been revealed that the formation of 1:1(CD/IL) stoichiometric inclusion complex is suggested itself by IL with α- and β-CDs. The variation of the thermodynamic parameters with guest size and state are used to draw inferences about contributions to the overall binding from the driving forces, viz., hydrophobic and hydrophilic interfaces, van der Waals force, H-bonding, electrostatic force, structural effect and configurational theory.
