摘要
树枝状化合物具有规整的结构,其分子体积、形状和功能基可在分子水平上精确控制[1].它的出现对于经典的有机高分子界是一个冲击,它是化学、生命科学和材料科学等多学科的交叉点,成为当前学术界的一大研究热点.我国这方面的研究起步较晚,至今仅有陈永明[2]、薄...
A liquid crystalline carbosilane dendrimer with S C * phase has been synthesized in successive steps, resulting in the formation of defined, unimolecular compound. Twelve biphenyl mesogenic units were attached on its periphery and it has a three dimentional, tree like starburst structure. Its phase behavior was K95S C *103Ch118I. Compared with its biphenyl mesogenic unit, 4 (2′ methylbutyl) 4′ ( ω hydroxyhexyl)azobenzene, which was melted at 128 ℃ and is not a liquid crystal, it is a good liquid crystal material with S C * phase.
