Patent ID: 7867629

Claim:
A derivative of heterocyclic compound having nitrogen atom represented by general formula (1): HAr-L-Ar 1 —Ar 2 (1) wherein HAr is one of the following groups: L represents a single bond, an arylene group having 6 to 60 carbon atoms and may have a substituent, a heteroarylene group having 3 to 60 carbon atoms and may have a substituent or a fluorenylene group which may have a substituent; Ar 1 represents a divalent aromatic hydrocarbon group represented by one of general formulae (43) to (54): wherein R 1 to R 102 each independently represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms and may have a substituent, an alkoxyl group having 1 to 20 carbon atoms and may have a substituent, an aryloxyl group having 6 to 40 carbon atoms and may have a substituent, a diarylamino group having 12 to 80 carbon atoms and may have a substituent, an aryl group having 6 to 40 carbon atoms and may have a substituent, a heteroaryl group having 3 to 40 carbon atoms and may have a substituent, or a diarylamino group having 18 to 120 carbon atoms and may have a substituent; and L′ represents a single bond or a group selected from the following groups: Ar 2 represents an aryl group which may optionally be substituted, wherein Ar 2 is one of the following groups: and the optional substituent to Ar 2 is selected from the group consisting of a halogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted alkoxyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryloxyl group having 6 to 40 carbon atoms, a substituted or unsubstituted diarylamino group having 12 to 80 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 40 carbon atoms.
