    摘要: An organic electroluminescence device includes: a cathode; an anode; and a single-layered or multilayered organic thin-film layer provided between the cathode and the anode. The organic thin-film layer includes at least one emitting layer. The at least one emitting layer contains at least one phosphorescent material and a host material represented by the following formula (1). Ra-Ar1-Rb  (1) In the formula, Ar1, Ra and Rb each represent a substituted or unsubstituted benzene ring or a condensed aromatic hydrocarbon ring selected from a substituted or unsubstituted naphthalene ring, a substituted or unsubstituted chrysene ring, a substituted or unsubstituted fluoranthene ring, a substituted or unsubstituted phenanthrene ring, a substituted or unsubstituted benzophenanthrene ring, a substituted or unsubstituted dibenzophenanthrene ring, a substituted or unsubstituted triphenylene ring, a substituted or unsubstituted benzo[a]triphenylene ring, a substituted or unsubstituted benzochrysene ring, a substituted or unsubstituted benzo[b]fluoranthene ring and a substituted or unsubstituted picene ring. Substituents for Ra and Rb are not aryl groups.
