Abstract

Some 4-(4-alkyloxybenzoyloxy)-4'-(S)-$\alpha$-chloro-alkanoyloxybiphenyls have been synthesized and their mesomorphic properties were studied. They show a ferroelectric chiral smectic C phase in addition to the chiral nematic and smectic A phase. We obtained a large spontaneous polarization exceeding $10^{-7}\textrm{cm}^2$ in new biphenyl ester series.

4-(4-Alkyloxybenzoyloxy)-4'-(S)-$\alpha$-halo-alkanoyloxybipeny1계열 액정화합물이 합성되고, 그들의 액정성질이 조사되었다. 합성된 바이페닐 에스터계열 화합물들은 키랄 스메틱 C상 뿐 아니라 키랄 네마틱 및 스메틱 A상을 나타내고, $10^{-7}\textrm{cm}^2$ 이상의 큰 자발분극을 나타내었다.
