Claim:
A liquid crystal composition, comprising a compound of Formula (1) and a chiral dopant, and exhibiting an optically isotropic liquid crystal phase: wherein in Formula (1), R 1 is hydrogen or a C 1-20 alkyl, wherein arbitrary —CH 2 — in the alkyl may be replaced by —O—, —S—, —COO—, —OCO—, —CH═CH—, —CF═CF—, or —C≡C—, and arbitrary hydrogen in the alkyl and the alkyl with arbitrary —CH 2 — replaced by —O—, —S—, —COO—, —OCO—, —CH═CH—, —CF═CF—, or —C≡C— may be replaced by halogen or a C 1-3 alkyl; rings A 1 , A 2 , A 3 , A 4 , and A 5 are independently a benzene ring, naphthalene ring, thiophene ring, piperidine ring, cyclohexene ring, bicyclo-octane ring, tetrahydronaphthalene ring, or a cyclohexane ring, where arbitrary hydrogen in the rings may be replaced by halogen, a C 1-3 alkyl, a C 1-3 alkoxy, or a C 1-3 haloalkyl, —CH 2 — in the rings may be replaced by —O— or —S—, —CH═ may be replaced by —N═; Z 1 , Z 2 , Z 3 , Z 4 , Z 5 , and Z 6 are independently a single bond or a C 1-4 alkylene, wherein arbitrary —CH 2 — in the alkylene may be replaced by —O—, —S—, —COO—, —OCO—, —CSO—, —OCS—, —CH═CH—, —CF═CF—, or —C≡C—, and arbitrary hydrogen in the alkylene and the alkylene with arbitrary —CH 2 — replaced by —O—, —S—, —COO—, —OCO—, —CSO—, —OCS—, —CH═CH—, —CF═CF—, or —C≡C— may be replaced by halogen, provided that at least one of Z 1 , Z 2 , Z 3 , Z 4 , Z 5 , and Z 6 is —CF 2 O—; L 1 and L 2 are independently hydrogen or halogen; X 1 is hydrogen, halogen, —C≡N, —N═C═S, —C≡C—C≡N, —SF 5 , or a C 1-10 alkyl, wherein arbitrary —CH 2 — in the alkyl may be replaced by —O—, —S—, —CH═CH—, or —C≡C—, and arbitrary hydrogen in the alkyl and the alkyl with arbitrary —CH 2 — replaced by —O—, —S—, —CH═CH—, or —C≡C— may be replaced by halogen; and l, m, n, o, and p are independently 0 or 1, and l+m+n+o+p≦4.
