Abstract

We describe synthesis of a novel liquid crystal based on 1,4-bis(biphenyl-4-yl)buta-1,3- dyine (BDPDA-OCx). This molecule exhibited a thermotropic liquid crystal phase. In particular, BDPDA-OC6 showed a sybotactic nematic phase. Little is known about this phase in the low molecular weight liquid crystal compound. We consider this characteristic phase transition behavior is derived from the effect of long mesogen moiety.
