Claim 1:
2. The compound according to claim 1,
wherein in the general formula (I), A1 and A2 each represent a group selected from the group consisting of:
(a) a 1,4-cyclyhexylene group, wherein one —CH2— or two or more nonadjacent —CH2— present in the group may be substituted by —O— or —S—;
(b) a 1,4-phenylene group, wherein one —CH═ or two or more nonadjacent —CH═ present in the group may be substituted by —N═;
(c) a 1,4-cyclohexenylene group, a bicyclo[2.2.2]octane-1,4-diyl group, a naphthalene-2,6-diyl group, a naphthalene-1,4-diyl group, a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, a 5,6,7,8-tetrahydronaphthalene-1,4-diyl group, a decahydronaphthalene-2,6-diyl group, an anthracene-2,6-diyl group, an anthracene-1,4-diyl group, an anthracene-9,10-diyl group, and a phenanthrene-2,7-diyl group, wherein a hydrogen atom present in each of these groups may be substituted by a fluorine atom or a chlorine atom, and one —CH═ or two or more —CH═ present in a naphthalene-2,6-diyl group, a naphthalene-1,4-diyl group, a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, a 5,6,7,8-tetrahydronaphthalene-1,4-diyl group, an anthracene-2,6-diyl group, an anthracene-1,4-diyl group, an anthracene-9,10-diyl group, or a phenanthrene-2,7-diyl group may be substituted by —N═; and
(d) a thiophene-2,5-diyl group, a benzothiophene-2,5-diyl group, a benzothiophene-2,6-diyl group, a dibenzothiophene-3,7-diyl group, a dibenzothiophene-2,6-diyl group, and a thieno[3,2-b]thiophene-2,5-diyl group, wherein one —CH═ or two or more nonadjacent —CH═ present in each of these groups may be substituted by —N═,
these groups may be unsubstituted or substituted by one or more substituents L3,
L3 each independently represent a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a pentafluorosulfanyl group, a nitro group, a cyano group, an isocyano group, an amino group, a hydroxyl group, a mercapto group, a methylamino group, a dimethylamino group, a diethylamino group, a diisopropylamino group, a trimethylsilyl group, a dimethylsilyl group, a thioisocyano group, or a linear alkyl group having 1 to 20 carbon atoms or a branched or cyclic alkyl group having 3 to 20 carbon atoms, in which one —CH2— or two or more —CH2— may be each independently may substituted by —O—, —S—, —CO—, —CS—, —COO—, —OCO—, —CO—S—, —S—CO—, —O—CO—O—, —CO—NH—, —NH—CO—, —CH═CH—COO—, —CH═CH—OCO—, —COO—CH═CH—, —OCO—CH═CH—, —CH═CH—, —CF═CF—, or —C≡C—,
oxygen atoms are not directly bonded to each other, and
any hydrogen atom in the alkyl group may be substituted by a fluorine atom.
