“…Polymerizable liquid crystals, also known as reactive mesogens, typically refer to molecules that use acrylic acid ester unit as terminal group, which can be rapidly crosslinked and polymerized under UV irradiation, fixing the optical anisotropy of the liquid crystals [1,2] . The polymerized thin film has good mechanical properties and thermal stability, and has been applied in fields such as viewing angle compensation and polarizer [3,4] . In addition, in optical waveguide devices such as VR and AR, polymerizable liquid crystals also show good application prospects [5][6][7] .…”

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.
