Abstract:
1. A compound represented by the following formula (1): wherein identical symbols in these formulas may have the same structure or they may have independently different structures; each P is independently a polymerizable group of any of formulas (2) to (6) above; each A 1 is independently 1,4-cyclohexylene, 1,4-cyclohexenylene, 1,4-phenylene, naphthalene-2,6-diyl, tetrahydronaphthalene-2,6-diyl, fluorene-2,7-diyl, or bicyclo[2.2.2]octane-1,4-diyl, where any —CH 2 — of these rings is optionally replaced with —O—, any —CH═ is optionally replaced with —N═, and any hydrogen is optionally replaced with a halogen, C1–5 alkyl or halogenated alkyl; each Z 1 is independently a single bond, —(CH 2 ) 2 —, —(CF 2 ) 2 —, —(CH 2 ) 4 —, —CH 2 O—, —OCH 2 —, —COO—, —OCO—, —CH═CH—, —CF═CF—, —C≡C—, —C≡C—COO—, —OCO—C≡C—, —CH═CH—COO—, —OCO—CH═CH—, —(CH 2 ) 2 —COO—, —OCO—(CH 2 ) 2 —, —C≡C—CH═CH—, —CH═CH—C≡C—, —OCF 2 —, or —CF 2 O—; each Z 2 is independently a single bond or C1–20 alkylene, where any —CH 2 — in the alkylene is optionally replaced with —O—, —S—, —COO—, or —OCO—; X 1 is hydrogen, a halogen, CF 3 or C1–5 alkyl; each X 2 is independently hydrogen, a halogen or C1–5 alkyl; m and n are each independently 0, 1 or 2; each p is 2 or 3; each q is 0 or 1; and when at least one Z 1 is —C≡C—, P is formula (3), (4) or (5).
