High Birefringence and Low Viscosity Liquid Crystals with Negative Dielectric Anisotropy

Fast response time is critical for reducing the image blurs in LCD TVs. A straightforward approach is to use thin cell with a high birefringence and low viscosity liquid crystal material. We have synthesized and evaluated the physical properties of some high birefringence, laterally difluorinated terphenyl compounds and mixtures. These mixtures exhibit a high birefringence (Dn 0.24) in the visi...

Optical birefringence of liquid crystals for label-free optical biosensing diagnosis

PURPOSE We present a polarization-sensitive optical detection platform for label-free quantitative optical biosensing diagnosis using liquid crystals (LCs). This is capable of determining quantitatively the optical birefringence of optical cells containing LCs, whose orientation depends on the immobilized biomolecules. PATIENTS AND METHODS This technique uses a polarization-dependent double-p...
