Abstract: A liquid crystalline carbosilane dendrimer with SC*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 K95Sc*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.

Key words: Dendrimer, Liquid crystal, SC*phase
