摘要：通过酰亚胺化和氯碘交换反应合成了3种含有碘和端基炔三官能团的AB2型单体,并由它们通过Sonogashira交叉偶联聚合反应制备了一系列具有烯二炔重复单元的超支化聚合物(HBEPs)。采用核磁(NMR)、傅里叶红外光谱(FT-IR)、凝胶渗透色谱(GPC)、动态光散射(DLS)、差示量热扫描(DSC)、紫外-可见(UV-Vis)和荧光光谱等测试手段对HBEPs的结构进行了一系列测试和表征,研究了主链中取代基对聚合物的物理和化学性能的影响。结果表明:HBEPs的支化度最高接近于1,其荧光特性与自身结构的共轭程度有关。
Three kinds of AB2 type monomers with terminal alkyne（A）and iodine（B）were synthesized from dichloromaleic anhydride by amidation with terminal alkynyl amine followed by chlorine-iodine exchange reaction.Starting from these AB2 monomers,a series of hyperbranched polymers with enediyne repeating unit（HBEPs）were synthesized via one-pot Sonogashira cross coupling polymerization reaction.The structure of these HBEPs was characterized by NMR,FT-IR,GPC,DLS,DSC,UV-Vis and fluorescence spectroscopy.The effects of substituents of backbone on the physical and chemical properties of these polymers were studied.Results show that the maximum degree of branching of HBEPs is close to 1.In addition,the fluorescence characteristics of HBEPs are related to its conjugation degree.
