Abstract:
An organic electroluminescence device includes: an anode; an emitting layer; and a cathode, the emitting layer containing a first material, a second material and a third material, the first material being a fluorescent material, the second material being a delayed fluorescent material, the third material having a singlet energy larger than a singlet energy of the second material.

Claim (Index 25):
The organic electroluminescence device according to  claim 12 , wherein the third material comprises a group represented by a formula (30f) below, where:\n Y 31 , Y 32 , Y 34 , Y 35 , Y 37  and Y 38  each independently represent a nitrogen atom or CR 32 ; \n Y 41  to Y 45 , Y 47  and Y 48  each independently represent a nitrogen atom, CR 34 , or a carbon atom bonded to another atom in the molecule of the third material; \n R 32  and R 34  each independently represent a hydrogen atom or a substituent, the substituent being selected from the group consisting of a halogen atom, a cyano group, a substituted or unsubstituted alkyl group having 1 to 30 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 30 ring carbon atoms, a substituted or unsubstituted trialkylsilyl group, a substituted or unsubstituted arylalkylsilyl group, a substituted or unsubstituted triarylsilyl group, a substituted or unsubstituted diarylphosphine oxide group, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, and a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, the substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms being a non-fused ring; \n Y 39  represents NR 33 , an oxygen atom or a sulfur atom; \n Y 49  represents NR 35 , an oxygen atom or a sulfur atom; \n R 33  and R 35  each independently represent a hydrogen atom or a substituent, the substituent being selected from the group consisting of a cyano group, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 ring carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkylthio group having 1 to 20 carbon atoms, a substituted or unsubstituted arylthio group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkylsilyl group having 3 to 50 carbon atoms, a substituted or unsubstituted arylsilyl group having 6 to 50 ring carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, and a substituted or unsubstituted heterocyclic group having 5 to 30 ring atoms, the substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms for R 33  and R 35  being a non-fused ring; and \n a wavy line shows a bonding position with another atom or another structure in the molecule of the third material.
