Patent ID: 7943209

Claim:
A liquid crystal molecule comprising a structure represented by Formula (1): wherein X 1 in Formula (1) is represented by Formula (2); X 2 in Formula (1) is a group selected from Formula (3); X 3 in Formula (1) is represented by Formula (4); and in Formulas (1) to (4), R 1 is a hydrocarbon group or an alkoxy group having a straight chain or a branched chain with 4 to 16 carbon atoms; R 2 is an organosiloxane or an organosilane with 1 to 6 silicon atoms that may have a branched chain; R 3 and R 4 different from each other are each H, F, Cl, Br, CN, CH 3 , CF 3 , or OCH 3 ; Y 1 and Y 2 are each -, —COO—, —CH 2 —, —CH 2 O—, —C 2 H 2 —, —C 2 —, or —CF 2 O—; Z 1 to Z 4 are each H, F, Cl, Br, OH, NO 2 , CN, CF 3 , CH 3 , C 2 H 5 , OCH 3 , or OC 2 H 5 ; at least one of Z 1 to Z 4 is CH 3 , C 2 H 5 , OCH 3 , or OC 2 H 5 ; Z 5 and Z 6 are each H, F, Cl, Br, OH, NO 2 , CN, or CF 3 ; Z 7 and Z 8 are each H, F, Cl, Br, OH, NO 2 , CN, or CF 3 , excluding the case in which both Z 7 and Z 8 are H; n is an integer from 1 to 6; * represents a chiral center; and - represents a linking group.
