含二茂铁结构单元的苯并菲盘状液晶的合成及介晶性
Synthesis and Mesomorphic Properties of Triphenylene-based Discogens with Ferrocene Moiety
【摘要】 通过两条合成路线制备了含二茂铁基的苯并菲盘状液晶化合物.差示扫描量热法(DSC)和热台偏光显微镜(POM)对化合物的介晶性研究结果显示,化合物具有柱状介晶相.
【Abstract】 2-ferrocenecarbonyloxy-3,6,7,10,11-pentakis(alkyloxy)triphenylenes were prepared from two different synthetic routes and their liquid crystalline properties were studied with differential scanning calorimetry and polarizing optical microscopy. The results show that all the ferrocene-containing triphenylenes exhibit columnar mesophase.
