抄録

Cyclodextrin (CD) polymers were synthesized from the reaction of native CDs with a hexamethylene diisocyanate (HDI) compound in a dried DMF solution. The obtained CD polymer contained a range of 8 - 14% N due to HDI by elemental analysis. The physical and chemical properties of the CD polymers were characterized by IR, solid state ¹³C NMR, TGA, and DSC, respectively. An HPLC column was prepared using the CD polymer with a carbamate linker by a slurry method. Separation of the phenol isomers was conducted using the CD polymer stationary phase and CD by HPLC. Furthermore, an inclusion complex of the phenol isomer was studied by FT-Raman spectroscopy. From the HPLC and FT-Raman results, inclusion phenomena of o-, m-, and p-nitrophenol onto CD and CD polymers were analyzed.
