A series of new carbosilane dendrimers was prepared by repeating a combination of hydrosilation and allylation on a core molecule, triallylphenylsilane. Subsequent hydroboration and oxidation of the dendrimers gave the polyol derivatives, which were treated with a mesogenic molecule, 6-(4-cyanobiphenyl-4'-oxy)hexanoyl chloride, to give new carbosilane dendrimers carrying mesogenic groups. It was found that the all carbosilane dendrimers exhibited liquid crystal phases. The effects of the dendrimer generations on the ranges of liquid crystal temperatures were investigated.

The Si-Ph bond of PhSi[(CH2)3SiMe2Bz] 3 (5) is cleaved with triflic acid to give TfOSi[(CH 2)3SiMe2Bz]3, which, in turn, reacts with triethylammonium chloride or potas

A series of new carbosilane dendrimers carrying cyanobiphenyl derivatives was prepared starting from the tertiary core molecule, triallylphenylsilane. The phase transition of the dendrimers depends on the dendrimer generation, and the spacer lengths were
