First claim

Opening claim text (preview).

The invention claimed is: 1. A compound represented by the following formula (1): R 4 —R 3 —Ar 1 —(—R 1 —Ar 2 —) n -N═N-Ar 3 —R 2   (1) wherein Ar 1 , Ar 2 , and Ar 3 each independently represent a 1,4-phenylene group optionally having a substituent or a divalent sulfur-containing aromatic heterocyclic group optionally having a substituent, and at least one of Ar 1 and Ar 2 has a fluorine atom as a substituent; n is an integer of 1 or 2; R 1 represents a single bond or at least one group selected from the group consisting of —OC(═O)—, —C(═O)O—, —C≡C—, —CH═CH—, —CH═N—, and —N═CH—; R 2 represents an alkylamino group optionally having a polymerizable group; R 3 represents at least one group selected from the group consisting of an alkanediyl group having 4 to 20 carbon atoms, an alkanediyloxy group having 2 to 20 carbon atoms, an alkanediyloxycarbonyl group having 2 to 20 carbon atoms, and an alkanediylcarbonyloxy group having 2 to 20 carbon atoms; R 4 represents a polymerizable group or a hydrogen atom; when n is 2, two R 1 s may be the same as or different from each other, and two Ar 2 s may be the same as or different from each other. 2. The compound according to claim 1 , wherein either one of Ar 1 and Ar 2 has one or two fluorine atoms as a substituent in the formula (1). 3. The compound according to claim 1 , wherein R 1 is a single bond in the formula (1). 4. The compound according to claim 1 , wherein n is an integer of 1 in the formula (1). 5. The compound according to claim 1 , wherein the polymerizable group is a radically polymerizable group. 6. A composition comprising the compound according to claim 1 . 7. A film comprising the compound according to claim 1 as a forming material. 8. A laminate comprising the film according to claim 7 . 9. A display device comprising the film according to claim 7 .
