Synthesis of liquid crystalline oligo(p-phenylene vinlyene)

The synthesis of oligo(p-phenylene vinylene) with mesogenic side chains is described, with the objective to explore highly ordered p-conjugated materials for functional properties. In the case of dimeric and tetrameric (p-phenylene vinylene) only a melt transition was observed while in the case of hexameric (p-phenylene vinylene) a liquid crystalline phase was found under the polarization microscope
