Low absorption liquid crystals for mid-wave infrared applications.

چکیده
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 °C), reasonably high birefringence (Δn~0.2), low visco-elastic coefficient, and modest dielectric anisotropy (Δε = -2.7). This compound serves as an important first example for future development of low-loss MWIR liquid crystals and devices.

Low loss liquid crystals for infrared applications
Seven fluorinated and chlorinated terphenyl compounds intended for mid-wave infrared (MWIR) applications are synthesised and two eutectic mixtures formulated, and their physical properties evaluated. In addition to low absorption, some desirable properties for MWIR applications include wide nematic range, high birefringence, large dielectric anisotropy and low viscosity. The fluorinated terphen...
متن کاملLow mid-infrared absorption tolane liquid crystals terminated by 2,2-difluorovinyloxyl: synthesis, characterization and properties
The synthesis and characterization of new 2,2-difluorovinyloxyl terminated tolane liquid crystals are reported. The mesomorphic properties, mid-wave infrared (MWIR) absorption and birefringence were investigated. The results show that these materials exhibit low absorption loss, a wide nematic phase range, a low melting point and high birefringence. The influences of fluorine substitution and t...
متن کاملLow absorption chlorinated liquid crystals for infrared applications
We report a wide nematic range and low absorption loss chlorinated liquid crystal mixture, designated as IR-M2, for mid-wave infrared applications. IR-M2 is quite transparent in the 3.8-5.0 μm window while keeping a high birefringence (Δn~0.194) in the infrared region and a modest dielectric anisotropy. For long-wave infrared applications, we propose another high Δn chlorinated cyanoterphenyl c...
متن کاملMid-wave infrared beam steering based on high-efficiency liquid crystal diffractive waveplates.
We demonstrated two liquid crystal diffractive waveplates: one optimized for near-infrared (1.06 µm), and another for mid-wave infrared (MWIR, 3~5 µm). By employing a low loss liquid crystal mixture UCF-M3, whose absorption loss is below 2% in the 4~5 µm spectral region, the grating achieves over 98% diffraction efficiency in a broad MWIR range. To switch the grating, both active and passive dr...

Perdeuterated 4’-pentyl-4-cyanobiphenyl ~D5CB! was synthesized and its physical properties evaluated and compared to those of 5CB. D5CB retains physical properties similar to those of 5CB, such as phase transition temperatures, dielectric constants, and refractive indices. An outstanding feature of D5CB is that it exhibits a much cleaner and reduced infrared absorption. Perdeuteration, therefor...
