HALOGEN-CONTAINING TRIPHENYLENE BASED MESOGEN COMPOUND CONTAINING A PHOTO-REACTIVE GROUP CAPABLE OF FORMING A FILM THROUGH A PHOTO CROSSLINKING REACTION OF ULTRAVIOLET IRRADIATION

摘要

PURPOSE: A halogen-containing triphenylene based mesogen compound is provided to manufacture a reinforcing film to a thin film because birefringence of high to obtain wide sight angle of a large screen of a liquid crystal display device.;CONSTITUTION: A halogen-containing triphenylene based mesogen compound is in chemical formula 1. In chemical formula 1, X is one selected from bromine, chlorine, and iodine, Y is one selected from O, NH, and S, and L is selected from -R-, -C(=O)-R-, -C(=O)-Ar-O-R- and C(=O)-Ar-NH-R-. In here, R is a linear or branched C1-20 alkylene group, Ar is a C6-30 arylene group, and Z is one selected from -OCOCHCH2, -OCOC(CH3)CH2, -OCOCHCH-phenyl, -OCOCHCH-furanyl, -NHCOCHCH2, -NHCOC(CH3)CH2, -NHCOCHCH-phenyl, and -NHCOCHCH-furanyl.;COPYRIGHT KIPO 2012
