摘要:用圆偏振光二向色性谱法研究了3种含氨酯基的壳聚糖衍生物的胆甾液晶螺旋性质.结果表明,3种衍生物的质量分数为65%的氯仿溶液都呈现胆甾液晶相.此外,CD谱观察结果显示侧基结构对其胆甾螺旋方向有明显的影响.

关键词: 壳聚糖, 衍生物, 胆甾相, 液晶, 螺旋结构, 圆偏光二向色性

Abstract: The helicoidal properties of three urethane derivatives of chitosan in cholesteric liquid crystalline phase were studied by means of circular dichroism spectroscopy.The 65% chloroform solutions of all three derivatives demonstrated cholesteric liquid crystalline phase.A strong influence of the substituent on the twist sense was investigated.

Key words: chitosan, derivatives, cholesteric phase, liquid crystals, helicoidal structure, circular dichroism
