Amylose, which is a linear polysaccharide consisting of α-(1,4)-linked D-glucopyranose units, is known to form inclusion complexes with various kinds of low-molecular-weight organic molecules such as iodine and dodecanoic acid in aqueous media by incorporating such guest molecules into the hydrophobic helical cavity. On the other hand, inclusion complex formation of amylose with polymeric guests has been believed to be difficult mainly due to the rigidity of the helical structure based on the intramolecular multiple hydrogen bonding. Recently, we have found that partially methylated amyloses, which have more flexible helical structures than the parent amylose, can efficiently form the inclusion complexes with poly(tetramethylene oxide)s in aqueous media. In this lecture, I will present our recent results on the inclusion complex formation between the partially methylated amyloses and various types of guest polymers and the structures of the resulting inclusion complexes. |
