Abstract:
通过将咔唑和芴衍生物之间进行Suzuki偶联反应得到大分子引发剂,再通过原子转移自由基聚合引入8-羟基喹啉和叔丁基功能化的丙烯酸酯类单体,得到了具有刚性主链柔性侧链结构的蓝光聚合物分子刷P2和P3.聚合物P2在四氢呋喃中的紫外吸收最大峰在330nm左右,薄膜的紫外吸收峰基本没有变化,聚合物P2在四氢呋喃中的荧光发射峰在460nm的蓝光区域,薄膜的荧光发射峰有10nm左右的蓝移.聚合物P3在四氢呋喃中的紫外吸收最大峰在355nm左右,薄膜的紫外吸收峰没有变化,荧光发射在430nm的蓝光区域,薄膜的荧光发射峰红移了50nm左右.对聚合物P2在不同温度、不同体积比水和四氢呋喃混合溶剂以及溶液pH值条件下自组装形成胶束的行为发现,聚合物P2在溶液pH值为11时,形成"核-壳"结构的胶束;在不同实验条件下聚合物P2自组装形成胶束的形貌也有较大区别.对聚合物P3不同实验条件下自组装形成胶束的行为发现,聚合物P3在体积比为32的四氢呋喃和水混合溶剂中更易形成稳定的胶束;聚合物P3的水溶性比聚合物P2差,这使该聚合物更易在水含量更高的混合溶剂中形成规整的球形胶束.
