Patent ID: 6936679

Claim:
A charge-transporting polymer represented by the following general formula (I-1) or (I-2): wherein each of Y and Z independently represents a bivalent hydrocarbon group; A represents a group represented by the following general formula (II-1), each of B and B′ independently represents the group —O—(Y—O) m —H or the group —O—(Y—O) m —CO-Z-CO—OR′ wherein R′ represents a hydrogen atom, an alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group, and each of Y and Z independently represents a bivalent hydrocarbon group, and m is an integer of 1 to 5, m is an integer of 1 to 5, and p is an integer of 5 to 5,000: wherein Ar represents a substituted or unsubstituted monovalent polynuclear aromatic ring having 3 to 10 aromatic rings or a substituted or unsubstituted monovalent condensed aromatic ring having 2 to 10 aromatic rings, X represents a substituted or unsubstituted bivalent aromatic group, T represents a bivalent linear hydrocarbon group having 1 to 6 carbon atoms or a bivalent branched hydrocarbon group having 2 to 10 carbon atoms, and each of k and n is an integer of 0 or 1.
