The results from X-ray diffraction, cross-polarity/magic-angle-spinning 13C NMR, differential scanning calorimetry, and Fourier transform infrared suggested that a channel-type structure was established in the inclusion complexes. The characterization results also revealed that the segments of poly(ethylene glycol) arms near the POSS cores were uncovered by the cyclodextrins, whereas the cyclodextrins were closely packed along the remaining portion of the poly(ethylene glycol) arms. Molecular dynamic simulation in a Dreiding force field with Cerius 2 software gave comparable results. © 2004 Wiley Periodicals, Inc.||Source Title:||Journal of Polymer Science, Part B: Polymer Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/87858||ISSN:||08876266|
