1. A compound represented by formula (1): wherein, in formula (1), all of a1 moieties of P1 and a2 moieties of P2 are identically a group selected from groups represented by formulas (P-1), (P-2) and (P-3), and in formula (P-1), M is hydrogen, fluorine, —CH3 or —CF3: S1 and S2 are independently a single bond or alkylene having 1 to 6 carbons, and in the alkylene, at least one of —CH2— may be replaced by —O—, —COO— or —OCO—, at least one of —CH2—CH2— may be replaced by —CH═CH— or —C≡C—, and in the group, at least one of hydrogen may be replaced by halogen; a1 and a2 are independently 0, 1, 2, 3 or 4, and a sum of a1 and a2 is 4; ring A1 is naphthalene, anthracene or phenanthrene, ring A2 is cyclohexyl, phenyl, naphthyl, anthracenyl or phenanthrenyl, and in the rings, at least one of hydrogen may be replaced by halogen, alkyl having 1 to 10 carbons, or alkyl having 1 to 10 carbons in which at least one of hydrogen is replaced by halogen; Z1 is a single bond, —CO—, —COO—, —OCO—, —CH═CH—, —C≡C—, —CH═C(CH3)—, —C(CH3)═CH—, —C(CH3)═C(CH3)—, —CH═CH—COO—, —OCO—CH═CH—, —C(CH3)═CH—COO—, —OCO—CH═CH(CH3)—, —CH═C(CH3)—COO—, —OCO—C(CH3)═CH—, —C(CH3)═C(CH3)—COO—, —OCO—C(CH3)═C(CH3)—, —CH═CH—CO—, —CO—CH═CH—, —CH═CH—CH2O—, —OCH2—CH═CH—, —CH═CH—OCH2— or —CH2O—CH═CH—; and b1 is 0, 1, 2, 3 or 4; wherein when b1 is 0, ring A1 is anthracene or phenanthrene. |
