| 摘 要： | 分别合成了两种侧链不同的聚肽热致液晶,PDLG和AzoPDLG.两者的主链均为刚直棒状的介晶基元,但PDLG的侧链为柔软的长烷基链,AzoPDLG的侧链则含有刚性的偶氮苯介晶基元和长链的间隔基.利用1H NMR、示差扫描量热分析和偏光显微镜对这些化合物的性质进行了分析与表征,并探讨了不同化学结构的侧链对热致液晶相变行为...

| Abstract: | Two thermotropic liquid crystalline polypeptides with different side chains,PDLG and AzoPDLG,were synthesized.Both of them have rigid-rod main chain,but PDLG has long alkyl side chains and AzoPDLG has side chains containing mesogenic azobenzene moieties and long spacers.The properties of these compounds were investigated by 1H NMR,DSC and POM.The thermotropic phase transition behaviors caused by the side chains with different chemical structures were also discussed.The results showed that PDLG could only fo... |
