Paper Abstract

Synthetic approach to novel groups of organsilicon liquid crystal polymers (and oligomers), i.e., polycarbosilanes, poly(cyclosiloxanes) and branched tetrahedral polysilanes (including their carbon centered analogues) is described as a method leading to products of well defined structure. These mesomorphic materials of comb- or star-shape types are made by hydrosilylation of mesogenic alkenes with the respective silicon-hydrogen bond containing polymers and oligomers. The effects of structural changes on the range and type of mesophase for these organometallic systems is shown to be not much different from those found for many organics. The synthetic results point to the ways of preparation of desired tailor-made organosilicon liquid crystals.
