Claim:
A derivative of heterocyclic compound having nitrogen atom represented by following general formula (I): wherein R represents a hydrogen atom, an aryl group having 6 to 60 carbon atoms which may have a substituent, a pyridyl group which may have a substituent, a quinolyl group which may have a substituent, an alkyl group having 1 to 20 carbon atoms which may have a substituent or an alkoxy group having 1 to 20 carbon atoms which may have a substituent; n represents an integer of 0 to 4; R 1 represents an aryl group having 6 to 60 carbon atoms which may have a substituent, a pyridyl group which may have a substituent, a quinolyl group which may have a substituent, an alkyl group having 1 to 20 carbon atoms which may have a substituent, or an alkoxy group having 1 to 20 carbon atoms and may have a substituent, with the proviso that the alkyl group is not propyl; L represents an arylene group having 6 to 60 carbon atoms which may have a substituent, a pyridinylene group which may have a substituent, a quinolinylene group which may have a substituent, or a fluorenylene group which may have a substituent, with the proviso that any substituent of L is not heteroaryl; Ar 1 represents a pyridinylene group which may have a substituent, a quinolinylene group which may have a substituent, or an arylene group selected from the following general formulae (1), (2), (4) to (10), (11) to (21), and (25), with the proviso that any substituent of Ar 1 is not heteroaryl; wherein general formulae (1), (2), (4) to (10) are: wherein each ring group may be bonded with a substituent selected from the group consisting of a halogen atom, an alkyl group having 1 to 20 carbon atoms which may have a substituent, an alkoxy group having 1 to 20 carbon atoms which may have a substituent, an aryloxy group having 6 to 40 carbon atoms which may have a substituent, an aryl group having 6 to 40 carbon atoms which may have a substituent; and when there is a plurality of substituents on the ring group, the substituents may be the same or different from each other; and L′ represents a single bond or a group selected from the following groups: and general formulae (11) to (21), and (25) are: wherein each condensed ring group may be bonded with a substituent selected from the group consisting of a halogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 40 carbon atoms; and when there is a plurality of substituents on the condensed ring group, the substituents may be the same or different from each other; Ar 2 represents an aryl group having 6 to 20 carbon atoms which may have a substituent, a pyridyl group which may have a substituent, a quinolyl group which may have a substituent, an alkyl group having 1 to 20 carbon atoms which may have a substituent, or an alkoxy group having 1 to 20 carbon atoms which may have a substituent, with the proviso that any substituent of Ar 2 is not heteroaryl.
