제목 Synthesis and properties of rod-type liquid crystalline materials with high birefringence based on hydroquinone core
초록 High birefringent liquid crystalline materials have been attracting interest for use in optical devices such as compensation films for wide viewing angle in LCD, liquid crystalline micro-lens array for 3D display, reflectors, and polarizers. The birefringence (Δn) of liquid crystal is mainly determined by the conjugation length, molecular shape, and polarizability so that we have been studying conjugation and polarizable parts of benzoate and tolane (phenyl-acetylene-phenyl) groups to induce high Δn. Here, we'll report the synthesis and properties of tolane bridged novel rod-type liquid crystalline materials based on hydroquinone core. And, thermotropic phase transition properties and high birefringence (> 0.3) with differential scanning calorimetry, polarized optical microscopy and opto-electrical measurement results will be discussed.
