Abstract:
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 (3): wherein A 18 ,A 19 ,A 20 ,A 21 ,A 22 ,A 23 ,A 24 ,A 25 ,A 26 ,A 27 ,A 28 ,A 29 ,A 30 ,A 31 ,A 32 , A 33 ,A 34 ,A 35 , A 36 ,A 37 , A 38 , A 39 , and A 40 each independently represent a carbon atom or a nitrogen atom; A 17 , A 22 ,A 27 ,and A 32 each represent a carbon atom having R″; R″ represents a substituent having an Sp 3 carbon atom at a bonding position thereof; 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, a silyl group having 3 to 18 carbon atoms or a phosphoryl group having 1 to 18 carbon atoms; and m represents an integer, further wherein the ring structure comprising A 37 , A 38 , A 39 , and A 40 comprises a substituent linked to A 38 or to A 40 , wherein the substituent linked to A 40 is an alkyl substituent having 1 to 18 carbon atoms, wherein said substituent is linked to A 40 when A 40 is a carbon atom, and wherein the substituent linked to A 38 is selected from the group consisting of an alkyl group having 1 to 18 carbon atoms, a halogen atom, a cyano group, a nitro group, a heterocyclic group having 2 to 10 carbon atoms, a silyl group having 3 to 18 carbon atoms or a phosphoryl group having 1 to 18 carbon atoms, wherein said substituent is linked to A 38 when A 38 is a carbon atom.
