The use of cationic dendronized polymers as a polyelectrolytic system for templating thermotropic liquid-crystalline phases (LC) via complexation and self-assembly with counter-charged ionic lipids is described. The topology of the LC phases resulting from the self-assembly process, their lattice parameter, and the interpenetration of lipid chains is discussed via birefringency analysis and small-angle
描述了使用阳离子树枝状聚合物作为聚电解质系统,通过络合和自组装与反电荷离子脂质对热致液晶相 (LC) 进行模板化。通过双折射分析和小角度 X 射线散射讨论了自组装过程产生的 LC 相的拓扑结构、它们的晶格参数和脂质链的相互渗透。根据树枝状聚合物的生成和烷基链的长度,观察到无定形、层状和柱状四方相。提出了一种结构模型,该模型解释了烷基链长度和聚合物生成的系统变化。由于离子络合的可逆性质,该过程证明与纳米多孔通道、仿生、运输、
