The results show that the liquid crystalline (LC) phase structures of the dendronized polymers containing dendritic azobenzene side groups depend strongly on the molecular weights (MWs) and the generation of dendritic azobenzene side groups. Compared the low MWs PG2 with the low MWs PG1, the degree of order in LC phase increased with increasing the generation of dendritic azobenzene side groups.
第一代和第二代树枝状聚合物,聚(2, 5-双[3, 5-二(4'-甲氧基-4-氧己氧基偶氮苯)苄基]氧羰基}苯乙烯)(PG1)和聚(2, 5 -bis 3, 5-di [3, 5-di (4'-methoxy-4-oxyhexyloxy azobenzo) benzyl] oxycarbonyl} 苯乙烯) (PG2) 被成功合成,并通过差示扫描量热法研究了它们的相结构( DSC)、偏光显微镜 (PLM) 和一维广角 X 射线衍射 (1D WAXD)。结果表明,含有树枝状偶氮苯侧基的树枝状聚合物的液晶(LC)相结构强烈依赖于分子量(MW)和树枝状偶氮苯侧基的生成。将低 MWs PG2 与低 MWs PG1 进行比较,
