摘要：A liquid crystalline carbosilane dendrimer has been synthesized in successive steps, resulting in the formation of defined, unimolecular compound. 12 AZO-meso-units were attached on its periphery and it has a three dimentional, tree-like, starburst structure. Its phase behavior was K64 S(X)115 S(A)123N138I. Compared with its AZO-meso-unit, 4-nitro-4'-(omega-hydroxyhexyl)-azobenzene, whose phase behavior was K122N132I, its phase range was enlarged about 64 degrees C and two more liquid crystalline phases S-A, S-X were found.
