Claim 9:
10. The organic electroluminescent device according to claim 1, wherein the second organic compound is represented by the following formula (101):, wherein at least one of R1 to R5 represents a cyano group, at least one of R1 to R5 represents a group represented by the following formula (111), and the balance of R1 to R5 each represent a hydrogen atom or a substituent,, wherein R21 to R28 each independently represent a hydrogen atom or a substituent, provided that at least one of the following conditions (A) and (B) is satisfied:
(A) R25 and R26 together form a single bond, and
(B) R27 and R28 together represent an atomic group that is necessary for forming a substituted or unsubstituted benzene ring, and
all or a part of the hydrogen atoms in the formula (101) may be 2H,
the substituent for the balance of R1 to R5 in the formula (101) and the substituent for R21 to R28 in the formula (111) are independently selected from the group consisting of a hydroxyl group, a halogen atom, a cyano group, an alkyl group having from 1 to 20 carbon atoms, an alkoxy group having from 1 to 20 carbon atoms, an alkylthio group having from 1 to 20 carbon atoms, an alkyl-substituted amino group having from 1 to 20 carbon atoms, an aryl-substituted amino group having from 12 to 40 carbon atoms, an acyl group having from 2 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a heteroaryl group having from 3 to 40 carbon atoms, a substituted or unsubstituted carbazolyl group having from 12 to 40 carbon atoms, an alkenyl group having from 2 to 10 carbon atoms, an alkynyl group having from 2 to 10 carbon atoms, an alkoxycarbonyl group having from 2 to 10 carbon atoms, an alkylsulfonyl group having from 1 to 10 carbon atoms, a haloalkyl group having from 1 to 10 carbon atoms, an amide group, an alkylamide group having from 2 to 10 carbon atoms, a trialkylsilyl group having from 3 to 20 carbon atoms, a trialkylsilylalkyl group having from 4 to 20 carbon atoms, a trialkylsilylalkenyl group having from 5 to 20 carbon atoms, a trialkylsilylalkynyl group having from 5 to 20 carbon atoms, and a nitro group.
