摘要:
An organic electroluminescent device is provided and includes: a cathode; an anode; and a light-emitting layer between the cathode and the anode. The light-emitting layer includes a compound represented by formula (1). In formula (1), L represents a linking group; A1, A2, A3, A4, A5, A6, A7, A8, A9, and A10 each independently represent a carbon atom or a nitrogen atom, provided that at least two of A1, A5, A6, and A10 each represent a carbon atom having R′; R′ represents a substituent having a carbon atom at a bonding position thereof; a plurality of Rs each independently represent a substituent; m represents an integer; and n represents an integer of 2 to 10.
