Abstract:
Provided is a conjugated block copolymer that is capable of morphology control and that can achieve superior conversion efficiency. A π-electron conjugated block copolymer contiguously or non-contiguously bonding polymer block (A) involving a monomer unit having in a portion of a chemical structure at least one heteroaryl skeleton selected from a thiophene, a fluorine, a carbazole, a dibenzosilole and a dibenzogermole; and a polymer block (B) involving a monomer unit similarly having at least one heteroaryl skeleton; wherein the polymer block (A) comprises a homopolymer block of a monomer unit having a substituent RnA that is an alkoxy group or an alkyl group having 1-18 carbon atoms, and the polymer block (B) comprises a copolymer block of at least two different each other types of monomer units having substituent RnB selected from an alkoxy group or an alkyl group having 1-18 carbon atoms, which may be substituted with an alkoxy group, a halogen atom, a hydroxyl group, an amino group, a thiole group, a silyl group, an ester group, an aryl group, hetero aryl group.
