Organic electroluminescence device
View Patent ↗An organic electroluminescence device includes: a pair of electrodes; and at least one organic layer including a light emitting layer, the light emitting layer being provided between the pair of electrodes, wherein at least one layer of the at least one organic layer contains a compound represented by formula (1): wherein each of Z 11 and Z 12 independently represents an aromatic heterocyclic ring or an aromatic hydrocarbon ring; R 11 represents a hydrogen atom or a substituent, provided that a plurality of R 11 s are the same or different; m represents an integer of 1 or more; and L 1 represents a single bond or an m-valent linking group and is linked to any one of C atoms in R 11 , Z 11 and Z 12 , provided that when m is 1, L 1 does not exist.
1. A compound represented by formula (4-5):
wherein each of X 451 and X 452 independently represents C—R 451 ;
R 451 represents a hydrogen atom or a substituent, provided that a plurality of R 451 s are the same or different;
each of A 451 to A 457 independently represents a nitrogen atom or C—R 452 ;
