摘要：
The present invention relates to the use of a compound represented by formula (I) in 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 the compound represented by formula (I); and
the light-emitting layer contains an iridium complex phosphorescent material:
wherein
R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 each represents a hydrogen atom or a substituent, and contiguous substituents of R 1 to R 8 may be bonded to each other to form a condensed ring;
R 9 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 R 1 to R 9 represents a deuterium atom or a substituent containing a deuterium atom.
