摘要

合成了几种线性共轭异硫氰酸酯(NCS)甲苯烷、联苯甲苯烷和双甾烷，并对其性能进行了评价。配制了这些化合物的共晶混合物。测量了随温度变化的双折射率、粘弹性系数和品质系数。这些异硫氰酸酯甲苯混合物在高温下表现出良好的高性能。强调了这些混合材料在激光光束导向、可调焦透镜和电信可变光衰减器等方面的潜在应用。

Molecular engineering of high-birefringence liquid crystals

Several linearly conjugated isothiocyanato (NCS) tolanes, biphenyl-tolanes and bistolanes were synthesized and their properties evaluated. Eutectic mixtures compromising these compounds were formulated. The temperature dependent birefringence, visco-elastic coefficient and figure-of-merit were measured. These isothiocyanato tolane mixtures exhibit a favorably high figure of merit at elevated temperatures. Potential applications of these mixtures for laser beam steering, tunable-focus lens and telecom variable optical attenuator are emphasized.
