Abstract

A light-emitting device comprising a pair of electrodes and a light-emitting layer or a plurality of organic layers comprising a light-emitting layer disposed therebetween, the light-emitting layer or at least one of a plurality of organic layers comprising the light-emitting layer comprising at least one compound represented by the following general formula (1): wherein each of Ar 11 , Ar 12 , Ar 13 , Ar 14 and Ar 15 represents an aryl group or a heteroaryl group; Ar represents a benzene ring, a naphthalene ring, a phenanthrene ring or an anthracene ring; at least one of Ar, Ar 11 , Ar 12 , Ar 13 , Ar 14 and Ar 15 is a condensed aryl group, a condensed or uncondensed heteroaryl group or a group comprising a condensed aryl group or a condensed or uncondensed heteroaryl group; Ar 11 , Ar 12 , Ar 13 , AR 14 and Ar 15 are not bonded to each other to form a ring; R 11 represents a substituent; and n 11 represents an integer of 0 or more.

Claims (5)

1 . A light-emitting device comprising a pair of electrodes and a light-emitting layer or a plurality of organic layers comprising a light-emitting layer disposed between said electrodes, said light-emitting layer or at least one of a plurality of organic layers comprising said light-emitting layer comprising at least one compound represented by the following general formula (1):

wherein each of Ar 11 , Ar 52 , Ar 13 , Ar 14 and Ar 15 represents an aryl group or a heteroaryl group; Ar represents a benzene ring, a naphthalene ring, a phenanthrene ring or an anthracene ring, at least one of Ar, Ar 11 , Ar 12 , Ar 13 , Ar 14 and Ar 15 is a condensed aryl group, a condensed or uncondensed heteroaryl group or a group comprising a condensed aryl group or a condensed or uncondensed heteroaryl group; Ar 11 , Ar 12 , Ar 13 , Ar 14 and Ar 15 are not bonded to each other to form a ring; R 11 represents a substituent; and n 11 represents an integer of 0 or more,

wherein said compound represented by said general formula (1) is represented by the following general formula (4):

wherein each of Ar 41 , Ar 42 , Ar 43 , Ar 44 , Ar 45 , Ar 46 , Ar 47 , Ar 48 , Ar 49 and Ar 50 represents an aryl group or a heteroaryl group; and Ar 41 , Ar 42 , Ar 43 , Ar 44 , Ar 45 , Ar 46 , Ar 47 , Ar 48 , Ar 49 and Ar 50 are not bonded to each other to form a ring.
