摘　　要：通过Gilch反应合成了结构新颖、含四官能团单元的超支化PPV聚合物P1～P3.聚合物的结构得到1 H NMR和元素分析结果的确证.通过热重分析(TGA)得知,该类非结晶相的聚合物热分解温度较高,分别为371.7、386.6和391.8℃.所合成的聚合物固态时的紫外吸收及荧光发射相对于液态的紫外吸收及荧光发射,波长有明显的红移现象,并且该聚合物具有宽吸收、窄发射的特征,在电致发光器件和聚合物太阳能电池器件中将有潜在的应用前景.Novel PPVs derivates were designed and successfully synthesized through Gilch reaction.The reaction intermediates and polymers were characterized by 1H NMR,GC-MS or GPC and Elemental Analysis（EA）.Their optical properties,thermal properties,electrochemical properties were investigated.These polymers are soluble in common organic solvents and they have good thermal stability.The onset weights loss temperature of the three polymers were found to be 371.7,386.6 and 391.8 ℃ for P1,P2 and P3,respectively.Compared with their spectra absorption in chloroform,the absorption bands of polymers P1,P2 and P3 in thin films were red-shifted.These polymers would be promising materials for luminescent materials or solar cells.
