摘要：

A partially fluorinated terphenyl liquid crystal with low absorption in both mid-wave infrared (MWIR) and near IR regions is developed and its properties evaluated. This compound exhibits a nematic phase (although only about 2 degrees C), reasonably high birefringence (Delta n similar to 0.2), low visco-elastic coefficient, and modest dielectric anisotropy (Delta epsilon = -2.7). This compound serves as an important first example for future development of low-loss MWIR liquid crystals and devices. (C) 2011 Optical Society of America
