Organic electroluminescent device |
摘要 |
An organic electroluminescent device includes a pair of electrodes; and an organic layer between the pair of electrodes, which includes a light-emitting layer, wherein the organic layer contains a compound represented by the following formula (I); and the light-emitting layer contains a iridium complex phosphorescent material:;
wherein R1, R2, R3, R4, R5, R6, R7 and R8 each represents a hydrogen atom or a substituent, and contiguous substituents of R1 to R8 may be bonded to each other to form a condensed ring; R9 represents an alkyl group, an alkenyl group, an aryl group, a hetero-aryl group, or a silyl group, and each of which group may be substituted with a substituent; and at least one of R1 to R9 represents a deuterium atom or a substituent containing a deuterium atom. |

1. An organic electroluminescent device comprising:
a pair of electrodes; and an organic layer between the pair of electrodes, which comprises a light-emitting layer, wherein the organic layer contains a compound represented by the following formula (I); and the light-emitting layer contains an iridium complex phosphorescent material: wherein R1, R2, R3, R4, R5, R6, R7 and R8 each represents a hydrogen atom or a substituent, and contiguous substituents of R1 to R8 may be bonded to each other to form a condensed ring; R9 represents an alkyl group, an alkenyl group, an aryl group, a hetero-aryl group, or a silyl group, and each of which group may be substituted with a substituent; and at least one of R1 to R9 represents a deuterium atom or a substituent containing a deuterium atom, wherein the iridium complex phosphorescent material contains a ligand bonding to an iridium atom via a carbene carbon. |
