To provide a diamine compound polymer having a fused aromatic group which is easy to simultaneously maintain basic various performances required as a charge transport material, that is, mobility, quantum efficiency, productivity, stability, handling properties and the like at a high level and can be utilized in various organic electronic devices.
The diamine compound polymer having a fused aromatic group is selected from the groups represented by formula (I-1) and (I-2) [wherein A is a structure represented by formula (II-1); Y and Z are each a divalent hydrocarbon group; B and B' are each -O-(Y-O)m-H or -O-(Y-O)m-CO-Z-CO-OR' (wherein R' is hydrogen, an alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group; m is an integer of 1-5; and p is a an integer of 5-5,000)].
