We have synthesized three novel flying-seed-like liquid crystals based on phthalocyaninato copper(II) (abbreviated as PcCu ) substituted by bulky groups (o- C1) PhS (i), (m- C1) PhS (j), [m, p-( C1)2] PhS (k)} instead of using long alkyl chains, in order to investigate their mesomorphism. Their phase transition behavior and the mesophase structures have been established by using a polarizing optical
我们合成了三种新型的基于酞菁铜(II)(缩写为PcCu)被大体积基团(o- C1) PhS (i), (m- C1) PhS (j), [m, p-( C1)2] PhS (k)} 代替使用长烷基链,以研究它们的介晶。它们的相变行为和中间相结构已经通过使用偏光光学显微镜、差示扫描量热仪和温度相关的小角 X 射线衍射仪确定。结果,[(oC1)PhS]8PcCu (8i), [(mC1)PhS]8PcCu (8j) 和 [m,p-(C1)2]PhS}8PcCu (8k) 显示一个 Coltet.o中间相 314.9~362.9 °C, a Col罗(P2m) 中间相在 287.4~334.2°C 和 Col罗(P2m) 中间相分别在 331.8~386.8°C。非常有趣的是,每种衍生物因此在非常高的温度下表现出柱状中间相。介晶显然起源于新的庞大群(i~k)。还值得注意的是,与相应的含 PhO
