SYNTHESIS OF REACTIVE MESOGENS BASED ON TRIPHENYLENE CORE WITH SULFIDE SIDE CHAIN

摘要

PURPOSE: A triphenylene-based reactive mesogen compound and a synthesizing method thereof are provided to produce a compensation film as a core material of a large screen wide viewing angle liquid crystal display, and to improve the liquid-crystalline phase at the high temperature. CONSTITUTION: A triphenylene-based reactive mesogen compound is marked with chemical formula 1. In the chemical formula 1, R is H, or a functional group of compounds marked with chemical formula 1-a~1-c. X is either O or NH. In the chemical formula 1-a, Z is the H, 4-CH3, 4-OCH3, 4-Br, 3-CH3, 3-OCH3, or 3-Br.
