Abstract
An organic EL device includes an anode, a cathode and an EL element arranged between the two. The EL element includes a substance represented by the following chemical formula: in which m, n=1-3; the substitute R is selected from a group consisting of t-butyl, phenyl, methylphenyl, naphehyl and heterocyclic compound. The EL element is highly efficient, lower-voltage operative and easy to be synthesized.
