1. An organic electroluminescent device comprising:
a cathode; an anode; and a light-emitting layer between the cathode and the anode, the light-emitting layer including a compound represented by formula (1): wherein 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 each optionally having a substituent, provided that at least two of A1, A5, A6, and A10 each represent a carbon atom having R′; R′ is selected from the group consisting of an alkyl group having 1 to 18 carbon atoms, an aryl group having 6 to 18 carbon atoms, a carbamoyl group having 2 to 18 carbon atoms, a cyano group, and an acylamino group having 2 to 10 carbon atoms; a plurality of Rs each independently represent an alkyl group having 1 to 18 carbon atoms, an aryl group having 6 to 18 carbon atoms, a halogen atom, a cyano group, a nitro group, a heterocyclic group having 2 to 10 carbon atoms, an acyl group having 2 to 12 carbon atoms, and a sulfonyl group having 1 to 12 carbon atoms, a silyl group having 3 to 18 carbon atoms or a phosphoryl group having 1 to 18 carbon atoms; m represents an integer; and n represents an integer of 2 to 10;
with the proviso that when A1 and A6 each represent a carbon atom having R′ and R′ is an alkyl group having 1 to 18 carbon atoms and n represents 2 and L is a 6-membered aromatic linking moiety and the n arylamine moieties are bonded to L at m-positions, then the plurality of Rs linked to L each independently represent a hydrogen atom or a substituent selected from the group consisting of an unsubstituted aryl group having 6 to 18 carbon atoms, a nitro group, a heterocyclic group having 2 to 10 carbon atoms, an acyl group having 2 to 12 carbon atoms, and a sulfonyl group having 1 to 12 carbon atoms, and further when A1 and A6 each represent a carbon atom having R′ and R′ is methyl and L is phenyl and n represents 2 and the n arylamine moieties are bonded to L at m-positions, then L must be substituted. |
