An organic EL device that has a high efficiency and a long service life, an electronic apparatus containing the organic EL device, and a compound capable of providing the organic EL device. The compound is specifically represented by the following general formula (1):
wherein in the general formula (1), Ar 1 represents an organic group A represented by the following general formula (A-1); Ar 2 represents the organic group A or an organic group B represented by the following general formula (B-1); and Ar 3 represents the organic group B or an organic group C represented by the following general formula (C-1), provided that in the case where both Ar 1 and Ar 2 are the organic groups A, the organic groups A may be the same as or different from each other,
in the general formula (A-1), R 1 and R 2 each represent a hydrogen atom, an alkyl group or an aryl group, and R 1 and R 2 may be bonded to each other to form a hydrocarbon ring; R 3 to R 6 each represent an alkyl group, a cycloalkyl group or an aryl group; and a, b, c and d each independently represent an integer of from 0 to 2, provided that R 3 and R 4 may be bonded to each other to form a hydrocarbon ring; and in the case where a or b is 2, adjacent groups of R 3 or adjacent groups of R 4 may be bonded to each other to form a hydrocarbon ring,
in the general formula (B-1), Ar 4 and Ar 5 each represent an arylene group; Ar 6 represents an aryl group; R 7 to R 9 each represent an alkyl group, a cycloalkyl group or an aryl group; e, f and g each represent an integer of from 0 to 2; and h and i each represent 0 or 1, provided that R 7 to R 9 may be bonded to each other to form a hydrocarbon ring; and in the case where e, f or g is 2, adjacent groups of R 7 , adjacent groups of R 8 or adjacent groups of R 9 may be bonded to each other to form a hydrocarbon ring,
in the general formula (C-1), Ar 7 represents an aryl group; R 10 represents an alkyl group, a cycloalkyl group or an aryl group; and j represents an integer of from 0 to 2, provided that in the case where j is 2, adjacent groups of R 10 may be bonded to each other to form a hydrocarbon ring. |
