  Novel Trifunctional Building Blocks for Fluorescent Polymers

  摘要：

  [GRAPHICS]Herein, we describe the synthesis of fluorescent 2-(arylsulfonyl)methacrylates and its polymers. These novel trifunctional monomers, possessing a fluorescent arylsulfonyl (ArSO2) group, an alkyl group (R), and a polymerizable olefin, serve as useful building blocks for functionalized fluorescent polymers.

  通过调整主链结构和灵活的间隔基长度来自组织胆固醇侧链液晶聚合物

  摘要：

  三种侧链液晶聚合物（SCLCP），其中胆甾醇型液晶元（Chol）与聚丙烯酸酯（PCholAC- m），聚甲基丙烯酸酯（PCholMC- m）和聚（2-乙烯基苯-1,4-二酸酯）连接通过自由基聚合成功地合成了通过不同长度（m = 0、2、4、6、8和10）的亚甲基间隔基形成的（PCholVA- m）主链。使用DSC，POM和SAXS详细研究了聚合物的相行为和结构。结果表明，通过改变主链结构和间隔区长度，Chol-SCLCPs表现出有趣的自组织。所述聚合物最初形成近晶A相，除了没有液晶相的PCholAC-0以外。接下来，聚合物PCholAC-m（m＝ 2、4、6）形成两层近晶A相，其中烷基尾部重叠（SmA 2）。在PCholAC- m（m = 8，10）中观察到两相共存结构，包括双层近晶A相（其中烷基尾部插入到液晶元中）（SmA d）和单层近晶A相，其中液晶元重叠（SmA 1）。对于PCholMC-
