| 摘要 |
An organic EL element of the invention has an organic compound layer, especially a light emitting layer which contains a compound of the following general formula (I): (Ar)m-L wherein Ar is an aromatic-bearing group, m is an integer of 2 to 6, the Ar groups may be the same or different, and L is a m-valent residue of a condensed polycyclic aromatic compound having 3 to 10 rings. Where L is a di- or trivalent residue derived from anthracene, at least one Ar is an aromatic residue derived from an alkynylarene. Where L is a tetravalent residue derived from naphthacene and Ar groups are attached at the 5-, 6-, 11- and 12-positions thereof, all the four Ar groups are not phenyl groups at the same time. The device of the invention sustains light emission of satisfactory luminance, especially at long wavelength for a long time.
