BLOCK COPOLYMER AND PHOTOELECTRIC CONVERSION ELEMENT |
摘要 |
<p>Provide are: a conjugated block copolymer capable of increasing the amount of optical absorption by a photoelectric conversion active layer and controlling the morphology thereof and capable of achieving excellent photoelectric conversion efficiency; and a photoelectric conversion element comprising a composition including an electron accepting material and this kind of conjugated block polymer. A À-electron conjugated block copolymer comprising: a polymer block (A) which involving a monomer unit having at least one heteroaryl skeleton selected from the group consisting of a fused À-conjugated skeleton, a fluorene, a carbazole, a dibenzosilole and a dibenzogermole containing at least one thiophene ring in a part of a chemical structure thereof; and a polymer block (B) involving a monomer unit of a thiophene-2,5-diyl group having a substituent at least at a 3-position thereof.</p> |
