Abstract:
1. A compound represented by formula (1): wherein, in formula (1), Ra and Rb are independently hydrogen, halogen or alkyl having 1 to 10 carbons, and in the alkyl, arbitrary —CH 2 — may be replaced by —O—, —S—, —CO— or —SiH 2 —, and arbitrary —(CH 2 ) 2 — may be replaced by —CH═CH— or —C≡C—; A 1 , A 2 , A 3 and A 4 are independently 1,4-cyclohexylene, 1,4-phenylene, cyclohexene-1,4-diyl, cyclohexene-3,6-diyl, decahydronaphthalene-2,6-diyl, 1,2,3,4-tetrahydronaphthalene-2,6-diyl or naphthalene-2,6-diyl, and in the rings, one of —CH 2 — may be replaced by —O—, —S—, —CO— or —SiH 2 —, and arbitrary —(CH 2 ) 2 — may be replaced by —CH═CH—, and in the rings, arbitrary hydrogen may be replaced by halogen, —CF 3 , —CHF 2 , —CH 2 F, —OCF 3 , —OCHF 2 or —OCH 2 F; Z 1 , Z 2 , Z 3 and Z 4 are independently a single bond or alkylene having 1 to 4 carbons, and in the alkylene, arbitrary —CH 2 — may be replaced by —O—, —S— or —SiH 2 —, and arbitrary —(CH 2 ) 2 — may be replaced by —CH═CH— or —C≡C—; m, n, q and r are independently 0, 1 or 2, and a sum of m, n, q and r is 1, 2, 3 or 4; and when a sum of m, n, q and r is 1, Ra and Rb are independently hydrogen, halogen or alkyl having 1 to 10 carbons, and in the alkyl, arbitrary —CH 2 — may be replaced by —O—, —S—, —CO— or —SiH 2 —, and arbitrary —(CH 2 ) 2 —may be replaced by —CH═CH— or —C≡C—; A 1 , A 2 , A 3 and A 4 are independently 1,4-cyclohexylene, 1,4-phenylene in which one or more of hydrogen is replaced by halogen, cyclohexene-1,4-diyl, cyclohexene-3,6-diyl, decahydronaphthalene-2,6-diyl, 1,2,3,4-tetrahydronaphthalene-2,6-diyl or naphthalene-2,6-diyl, and in the rings, one of —CH 2 — may be replaced by —O—, —S—, —CO—, or —SiH 2 —, and arbitrary —(CH 2 ) 2 — may be replaced by —CH═CH—, and in the rings, arbitrary hydrogen may be replaced by halogen, —CF 3 , —CHF 2 , —CH 2 F, —OCF 3 , —OCHF 2 or —OCH 2 F; and Z 1 , Z 2 , Z 3 and Z 4 are independently a single bond or alkylene having 1 to 4 carbons, and in the alkylene, arbitrary —CH 2 — may be replaced by —O—, —S— or —SiH 2 —, and arbitrary —(CH 2 ) 2 — may be replaced by —CH═CH— or —C≡C—.
