摘要
以蒽为起始原料,经溴代反应和Witting-Horner反应制得单体9,10-双[2-(1-辛基-1H-吡咯-2-基)乙烯基]蒽(3);3与芳酸缩聚合成了一个新型的蒽类聚方酸菁(4),其结构和性能经UV-Vis,1HNMR,13CNMR,IR,XRD,SEM和TG表征。4在氯仿中的λmax位于700nm;4为非晶态结构;4的初始分解温度为297.1℃。
A key monomer,9,10-bis[2-(1-octyl-1H-pyrrol-2-yl)]-vinylanthracene(3),was prepared by bromination and Witting-Horner reaction from anthracene.A novel polysquaraine(4) was synthesized by polymerization reaction of 3 with squaric acid.The structure and properties of 4 were characterized by UV-Vis,1H NMR,13C NMR,IR,XRD,SEM and TG.Properties of 4 were as follows: λmaxwas 700nm in chloroform,non-crystalline structure,the initial decomposition temperature was 297.1 ℃.
