Liquid Crystalline Oligosilanes with Alkoxybiphenyl Groups
Oligosilane derivatives, ROC<SUB>12</SUB>H<SUB>8</SUB>(SiMe<SUB>2</SUB>)<SUB>n</SUB>C<SUB>12</SUB>H<SUB>8</SUB>OR, were synthesized by treatment of α,ω-dichloropermethyloligosilanes with Grignard reagents derived from 4-alkoxy-4′-bromobiphenyls. Oligosilanes with n = 6; R = C<SUB>8</SUB>H<SUB>17</SUB> and n = 6; R = C<SUB>10</SUB>H<SUB>21</SUB> showed smectic B and E phases, respectively.
