两种[对苯乙炔-2,5-二(十二烷氧基)对苯乙炔]共聚物的合成及性能研究

Synthesis and Properties of Two Kinds of Poly( p phenylene vinylene co 2,5 didodecyl p phenylene vinylene)

用含氯前聚物路线和Ｈｅｃｋ反应分别合成［对苯乙炔－２，５－二（十二烷氧基）对苯乙炔］无规共聚物及交替共聚物．由元素分析、凝胶渗透色谱、吸收光谱及ＤＳＣ对其进行表征，研究了共聚物的组成与导电率、溶解性及发光性能的关系．比较了无规共聚物与交替共聚物在性能上的差别．

Random copolymers of P(PV DDOPV) were synthesized via chlorine precursor route, whereas alternating copolymer of P(PV DDOPV) was obtained through Heck reaction. The two kinds of copolymers were characterized by elemental analysis, GPC, DSC and absorption spectra. The effect of charging ratio on conductivity, solubility and fluorescent properties was studied. Difference of properties between the random copolymer and alternating copolymer was compared.
