Claims18
An organic electronic material comprising:
- a charge transporting polymer which has a branched structure and has a structural unit having a structure represented by Formula (1):
- in the formula, Ar's each independently represent an aromatic ring group, Ra's each independently represent a hydrogen atom, a substituent, or a binding site with another structure, Rb's each independently represent a substituent, and n's each independently represent an integer of 0 or more, where at least one of Ra's is a binding site with another structure.
An organic electronic material comprising:
- a charge transporting polymer which has a branched structure and has a structural unit having a structure represented by Formula (1),
- wherein the branched structure has at least one structural unit B and at least three or more structural units L bonded to the one structural unit B:
- in the formula, Ar's each independently represent an aromatic ring group, Ra's each independently represent a hydrogen atom, a substituent, or a binding site with another structure, Rb's each independently represent a substituent, and n's each independently represent an integer of 0 or more, where at least one of Ra's is a binding site with another structure.
