| Abstract: | Highly polar liquid crystals with very low birefringence were synthesized by a reaction sequence starting with the radical addition of a secondary alcohol to pentafluoropropene and perfluoropropene, respectively. The mesophases and electrooptical properties of the new materials were interpreted using a detailed computational analysis of the conformational equilibrium. |
