• (in the formula, R represents an alkyl group having 1 to 15 carbon atoms or an alkenyl group having 2 to 15 carbon atoms, and one —CH2— or two or more unadjacent —CH2— present in the group may be substituted by —O—, —S—, —COO—, —OCO—, or —CO—;
• A1 and A2 each independently represent a group selected from the group consisting of
• (a) a 1,4-cyclohexylene group (one —CH2— or two or more unadjacent —CH2— present in the group may be substituted by —O— or —S—),
• (b) a 1,4-phenylene group (one —CH═ or two or more unadjacent —CH═ present in the group may be substituted by —N═, and a hydrogen atom present in the group may be substituted by a fluorine atom), and
• (c) a naphthalene-2,6-diene group (a hydrogen atom present in the group may be substituted by a fluorine atom);
• Z1 and Z2 each independently represent —CH2O—, —OCH2—, —CF2O—, —OCF2—, —CH2CH2—, —CF2CF2—, —CH═CH—, —CF═CF—, —C≡C—, or a single bond;
