The invention relates to poly(phenylene vinylene) polymers substituted with dendritic sidechains to enhance main-chain separation in the solid state. The polymers are synthesized by the Heck polymerization and have a weight-average molecular weight of 20,000 to 60,000 Daltons. The polymers are self-ordering in the solid state and have thermotropic liquid crystalline phases. The polymers show enhanced photoconductivity, better charge transport capability and improved polarized light emission.
本发明涉及用树枝状侧链取代的聚苯基
乙烯聚合物,以提高固态下主链的分离度。这种聚合物是通过赫克聚合法合成的,其重量平均分子量为 20,000 至 60,000 道尔顿。这种聚合物在固态下具有自排序性,并具有热致性液晶相。这些聚合物具有更强的光电导性、更好的电荷传输能力和更高的偏振光发射率。
