Autor: Shin-Tson Wu, A. Spadło, Kung-Lung Cheng, Jun Li, Roman Da˛browski, Sebastian Gauza, Yu‐Nan Tzeng

Publikováno v: Liquid Crystals. 32:1077-1085

The molecular structures and physical properties of several single‐ and double‐fluorinated isothiocyanatotolane, isothiocyanatocyclohexyltolane, and isothiocyanatoterphenyl compounds are reported. Two eutectic mixtures comprising these compounds

Autor: Janet R. Wu, Fang Du, Shin-Tson Wu, A. Spadło, N. Janarthanan, Sebastian Gauza, Roman Da˛browski, Chain-Shu Hsu

Publikováno v: SID Symposium Digest of Technical Papers. 34:1054

In this paper, we described some isothiocyanato tolane liquid crystals (LCs) that exhibit a high birefringence and reasonably low viscosity. We evaluated the phase transition temperatures, birefringence (Δn) and visco-elastic coefficient of several

20.4: Threshold and V-Shape Switching Orthoconic Antiferroelectric Liquid Crystals for High Contrast Display

Autor: Krzysztof Czupryński, W. Drzewiński, Roman Da˛browski, Per Rudquist, Sebastian Gauza, Sven T. Lagerwall

Publikováno v: SID Symposium Digest of Technical Papers. 33:770

Two types of multi-component FLC mixtures for high contrast displays were developed. These mixtures could exhibit either threshold or thresholdless (V-shape) behavior depending on the ratio of the anticlinic to synclinic compounds. The phase sequence
