Complexation of pyrene by poly(allylamine) with pendant beta-cyclodextrin side groups

Article Abstract:

A study was conducted to determine the complexation of pyrene into the cavity of beta-cyclodextrin (beta-CD) in aqueous solutions of pure beta-CD and b-CD replaced poly(allylamine) using fluorescence spectroscopy. It was established that intensity changes of the pyrene fluorescence based on the complexation by beta-CD was significant in the analysis of the steady-state fluorescence data. Results showed that complexation of pyrene with CD polymers shifted to lower concentrations with higher degree of substitution and increased within a lower concentration range.

Preparation and characterization of inclusion complexes of poly(propylene glycol) with methylated cyclodextrins

Article Abstract:

Complex formation between methylated cyclodextrins (CDs) and poly(propylene glycol) (PPG) in water is studied. Results show that PPG forms inclusion complexes with DM-beta-CD. Complex formation occurs in two steps wherein PPG solubilizes in a DM-beta-CD aqueous solution and then DM-beta-CD-PPG complex crystallizes. PPG solubility in water increases with the addition of DM-beta-CD while interaction between PPG and the inside shell of DM-beta-CD cavities was is also observed.

Novel prediction for the driving force and guest orientation in the complexation of alpha- and beta-cyclodextrin with benzene derivatives

Article Abstract:

A study was conducted to determine the driving forces and the guest orientation for the complexation of alpha and beta-cyclodextrins (CD) with mono and 1,4-disubstituted benzenes. Novel equations were utilized to carry out the study. Results indicated that van der Waals force has a critical function in alpha-CD complexation and that hydrophobic interactions have major roles in beta-CD complexation.
