perfluoroaromatic isolation groups, were successfully prepared, via the palladium-catalyzed Sonogashira coupling reaction. Among them, P2, due to the presence of the self-assembly effect between the perfluoroaromatic and chromophore moieties, demonstrated much larger NLO effect (d33 value of 162.3 pm/V) and better stability with onset temperature for decay (111 °C). The research on the polymer conformation
通过钯催化的Sonogashira偶联反应,成功制备了四个包含不同芳族或全氟芳族分离基团的新的聚亚芳基乙炔基P1 - P4。其中,由于全氟芳族和发色团部分之间存在自组装效应,P2表现出更大的NLO效应(d 33值为162.3 pm / V),并且在开始衰变温度(111°C)下具有更好的稳定性。 。对聚合物构象的研究表明,不同位置的全氟苯基对NLO系数的影响不同,这为设计性能更好的NLO聚合物提供了一些有用的信息。
