Synthesis and Mesomorphism of α,ω-Diphenylpermethyl-oligosilanes

α,ω-Dipehnylpermethyloligosilanes, Ph(SiMe2)nPh where n = 12 (3), and 13 (4), showed the mesophases in the range of 126-139 and 127-155 deg C, respectively. In the mesophases, the silicon chains adopted the all-trans conformation and were perpendicular to the layer plane and hexagonally ordered within the layer. Furthermore, the phenyls at both ends of the silicon chain were interdigitated between the neighboring layers.

Synthesis and mesomorphic properties of 1,10-dialkylpermethyldecasilanes

Decasilanes, R(SiMe2)10R where R = Et, Pr, and Bu, show the enantiotropic mesophase with a multilayer interdigitated structure. In the mesophase, the silicon chains adopt an almost all-trans conformation, and the decasilanes show absorption bands with maxima at 293 (R = Et) and 294 nm (R = Pr and Bu).
