Abstract

Crosslinked polycarbosilanes with mesogenic side chains have been prepared by hydrosilylation reaction of poly(1-methyl- 1-silylenemethylene) and the mixture of one and two functional terminal alkenes bearing promesogenic groups. All synthesized networks exhibit SmC* phase in wide temperature ranges. Their LC properties were compared with side chain uncrosslinked polycarbosilanes with the same general chemical structure. In order to make the temperature ranges of generated mesophase wider, the mixtures of crosslinked and uncrosslinked LC polycarbosilanes have been prepared and studied.
