<p>Disclosed is a polymer which has high singlet and triplet excitation levels, has excellent charge transport capability and electrochemical stability, enables lamination, is less susceptible to decomposition or the like, and can provide a homogenous film quality. Also disclosed are: an organic electroluminescence element material; a composition for an organic electroluminescence element; an organic electroluminescence element which has high luminous efficiency, can be driven at a low voltage, and has high driving stability; and a display device; and a lighting device. The polymer has a repeating unit represented by general formula (1) and a crosslinkable group. In general formula (1), Ar11 to Ar13 each independently represent a divalent aromatic group; Ar14 and Ar15 each independently represent an aromatic group; Ar16 and Ar17 each independently represent a direct bond or a divalent aromatic group; R11 and R12 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, or an aromatic group; and r represents an integer of 0 to 5. R11 and R12 may be combined with each other to form a ring structure. The crosslinkable group may be contained in the repeating unit represented by general formula (1).</p> |
