Claim 0:
1. An arylamine-fluorene alternating copolymer comprising a structural unit (A) represented by Chemical Formula (1):, wherein, in Chemical Formula (1), each occurrence of R1 to R4 independently represents a hydrogen atom or a hydrocarbon group having 1 to 16 carbon atoms,
L1 represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 25 carbon atoms or a substituted or unsubstituted divalent aromatic heterocyclic group,
x is 0, 1, or 2 and when x is 2, each occurrence of L1 may be the same or different, respectively,
L2 represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 25 carbon atoms or a substituted or unsubstituted divalent aromatic heterocyclic group, wherein L2 may form a ring with Ar1,
Ar1 represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 25 carbon atoms, or a substituted or unsubstituted divalent aromatic heterocyclic group, and forms a ring with L2, and
Ar2 represents an aromatic hydrocarbon group or an aromatic heterocyclic group having 6 to 25 carbon atoms wherein the aromatic hydrocarbon group or the aromatic heterocyclic group is substituted with a linear hydrocarbon group having 1 to 12 carbon atoms or a branched hydrocarbon group having 1 to 12 carbon atoms.
