Synthesis of low covered polyrotaxane based on poly(propylene glycol) and methyl-β-cyclodextrin |
| 초록 |
Low covered polyrotaxane was synthesized from 10:1 molar ratio of methyl-β-cyclodextrin (Me-β-CD) and poly(propylene glycol) (PPG) with a molecular weight of 1000, and expected to have higher elongation properties than full covered polyrotaxane because of easier movement of ring structure along the main chain. Tetra-amine PPG was pre-synthesized by the reaction of carbonyldiimidazole (CDI) and tris(2-amino-ethyl)amine (TA). In addition, Me-β-CD was threaded in PPG chain and end capping process was carried out using 2,4,6-trinitrobenzene sulfonic acid (TNBSA). The low covered polyrotaxane and every intermediate were characterized by FT-IR and 1H-NMR spectroscopies. |
