Patent ID: 7935395

Claim:
A liquid crystal molecule having a structure represented by the following general formula (1): wherein X 1 is a group selected among groups represented by the following formula (2): X 2 is represented by the following formula (3): R 1 represents a linear or branched hydrocarbon group or an alkoxy group each having from 4 to 16 carbon atoms; R 2 represents an optionally branched organosiloxane or organosilane having from 1 to 6 silicon atoms; R 3 and R 4 are different from each other and each represents H, F, Cl, Br, CN, CH 3 , CF 3 or OCH 3 ; Y 1 represents -, —COO—, —CH 2 —, —CH 2 O—, —C 2 H 2 —, —C 2 — or —CF 2 O—; Z 1 to Z 4 each represents H, F, Cl, Br, OH, NO 2 , CN, CF 3 , CH 3 , C 2 H 5 , OCH 3 or OC 2 H 5 ; Z 5 to Z 7 each represents H, F, Cl, Br, OH, NO 2 , CN or CF 3 , provided that Z 5 , Z 6 and Z 7 do not represent H at the same time; n represents an integer of from 1 to 6; * represents a chiral center; and - means a connecting group.
