Organic electroluminescent element and material for organic electroluminescent elements

An organic electroluminescence device includes: a cathode; an anode; and an organic thin-film layer having one or more layers and provided between the anode and the cathode, in which the organic layer includes an emitting layer. The emitting layer includes a first host material, a second host material and a phosphorescent dopant material. The first host material is a compound represented by a formula (1A). The second host material is a compound represented by a formula (2A).

BIS-CARBAZOLE DERIVATIVE, MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT USING SAME

A biscarbazole derivative of the invention is represented by a formula (1A or (1B) below. In the formula (1A) or (1B): A1 represents a substituted or unsubstituted nitrogen-containing heterocyclic group having 1 to 30 ring carbon atoms; A2 represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, or substituted or unsubstituted nitrogen-containing heterocyclic group having 1 to 30 ring carbon atoms; X1 and X2 each are a linking group; Y1 to Y4 each represent a substituent; p and q represent an integer of 1 to 4; and r and s represent an integer of 1 to 3.
