Compound having fluorinated naphthalene structure and liquid crystal composition of the same

A compound represented by general formula (1),

• (in the formula, R represents an alkyl group having 1 to 15 carbon atoms or an alkenyl group having 2 to 15 carbon atoms;
• one —CH2— or two or more non-adjacent —CH2— in the groups may be each independently substituted with —O—, —S—, —COO—, —OCO—, or —CO—;
• A1 to A4 are each independently selected from the group consisting of
• (a) a 1,4-cyclohexylene group (one —CH2— in this group may be substituted with —S— and two or more non-adjacent —CH2— in this group may be each independently substituted with —O— or —S—) and
• (b) a 1,4-phenylene group (one —CH═ or two or more non-adjacent —CH═ in this group may be substituted with —N═, and a hydrogen atom in this group may be substituted with a fluorine atom or a chlorine atom);
• Z1 to Z4 each independently represent —CF2O—, —OCF2—, —CH2CH2—, —CF2CF2—, —CH═CH—, —CF═CF—, —C≡C—, or a single bond, and at least one of Z1 to Z4 present in the compound represents —CF2O— or —OCF2—;
• Xa to Xd each independently represent a hydrogen atom, a fluorine atom, or a chlorine atom;
• and
• n represents 0 or 1).
