Abstract:
The organic electroluminescence device includes an anode, a cathode, and at least an emitting layer between the anode and the cathode. 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 (1) below and the second host material is a compound represented by a formula (2) below.

Claim (Index 1):
An organic electroluminescence device, comprising:\n an anode; a cathode; and at least an emitting layer between the anode and the cathode, the emitting layer comprising: a first host material: a second host material; and a phosphorescent dopant material, wherein the first host material is a compound represented by a formula (1) below, and the second host material is represented by a formula (2) below, where: Z 1  represents a cyclic structure fused at a of the formula (1) and represented by the formula (1-1) or (1-2); Z 2  represents a cyclic structure fused at b of the formula (1) and represented by the formula (1-1) or (1-2); at least one of Z 1  and Z 2  is represented by the formula (1-1); M 1  represents a substituted or unsubstituted nitrogen-containing heteroaromatic ring having 5 to 30 ring atoms; L 1  represents a single bond or a linking group, the linking group being one or a combination of a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, and a cycloalkyl group having 5 to 30 ring carbon atoms; and m is 1 or 2, where: c, d, e, fare fused at a or b in the formula (1); R 11  and R 31  each independently represent a hydrogen atom, a halogen atom, a cyano group, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, a substituted or unsubstituted alkyl group having 1 to 30 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 30 carbon atoms, a substituted or unsubstituted alkynyl group having 2 to 30 carbon atoms, a substituted or unsubstituted alkylsilyl group having 3 to 30 carbon atoms, a substituted or unsubstituted arylsilyl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted aryloxy group having 6 to 30 ring carbon atoms; a plurality of R 11  are mutually the same or different; a plurality of R 31  are mutually the same or different; adjacent groups of R 11  are optionally bonded with each other to form a ring; X 3  is a sulfur atom, an oxygen atom or N\u2014R 32  or C(R 32 ) 2 ; and R 32  represents the same as R 11  and R 31 , where: R 2  independently represents a hydrogen atom, a halogen atom, a cyano group, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, a substituted or unsubstituted alkyl group having 1 to 30 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 30 carbon atoms, a substituted or unsubstituted alkynyl group having 2 to 30 carbon atoms, a substituted or unsubstituted alkylsilyl group having 3 to 30 carbon atoms, a substituted or unsubstituted arylsilyl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted aryloxy group having 6 to 30 ring carbon atoms; p and q are independently an integer of 0 to 4; a plurality of R 2  are mutually the same or different; adjacent groups of R 2  are optionally bonded with each other to form a ring; L 2  represents a single bond or a linking group, the linking group being one or a combination of a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, and a cycloalkyl group having 5 to 30 ring carbon atoms; and FA represents a substituted or unsubstituted fused aromatic cyclic group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted fused aromatic heterocyclic group having 5 to 30 ring atoms.
