以叠氮基修饰的超支化共聚物PG-b-PBAMO-b-PG和10,11-二氢化奎宁为原料,通过“click”化学反应合成了一种新型侧链含有奎宁的光学活性两亲超支化嵌段共聚物PG-b-PBTQMO-b-PG.用傅里叶转变红外光谱(FT-IR)和核磁共振氢谱(1HNMR)对产物结构和组成进行了表征,并利用圆二色谱法研究了手性共聚物的光学活性.%A new optically active amphiphilic hyperbranehed block copolymer bearing quinine pendants pol-yglyeerol-b-poly [3,3-bis(triazolyl-L-quinine) methyl oxetane]-b-polyglycerol (PG-b-PBTQMO-b-PG) was synthesized by" click" reaction of azido-modified polyglycerol-b-poly(3,3-bis(azidomethyl) oxetane)-b-polyglycerol (PG-b-PBAMO-b-PG) hyperbranched eopolymer and 10,11-didehydro quinine.The Fourier transform infrared spectrum(FT-IR) and 1H nuclear magnetic resonance spectroscopy(1HNMR)were used to confirm its structure and composition.Additionally,the solution properties of this chiral copolymer were stu-died by circular dichroism(CD) spectroscopy.
