P‐13.10: Synthesis and properties of polymerizable liquid crystals based on bistolane

New series of polymerizable liquid crystals based on bistolane core and different lateral substituent groups were synthesized and characterized by 1 H‐NMR. The properties of these compounds were tested by DSC, POM and Abbe refractometer. The results indicate that all of these compounds display stable nematic phase, and the introduction of lateral substituents has a significant impact on the phase behaviour and birefringence. These newly compounds present higher birefringence (0.36~0.49) than that of the commercial compounds RM257 because of the extended π‐ conjugated.
