Abstract
α-Cyclodextrin having cinnamamide at 6- or 3-positions (6-CiNH-α-CD, 3-CiNH-α-CD) and β-cyclodextrin with cinnamamide on 6-position (6-CiNH-β-CD) have been prepared. Supramolecular structures were formed in the solid state or aqueous solutions and characterized by measurements of NMR and vapor pressure osmometry (VPO). The results indicate that 6-CiNH-β-CD formed insoluble supramolecular polymers in the solid state, while 6-CiNH-α-CD and 3-CiNH-α-CD formed supramolecular complexes in aqueous solutions. 6-CiNH-α-CD was found to form a dimer in an aqueous solution. 3-CiNH-α-CD formed intermolecular complexes to give supramolecular polymers. The differences of the position of guest part on cyclodextrins caused to give a variety of supramolecular structures in aqueous solutions.
