Title:
BLOCK COPOLYMER AND PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/133793
Kind Code:
A1
Abstract:
Provided 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 using this kind of conjugated block polymer. A pi-electrode conjugated block copolymer comprises: a polymer block (A) comprising a monomer unit having at least one heteroaryl skeletal structure selected from a group comprising a fused-ring pi-conjugated structure including at least one thiophene ring in one part of the chemical structure thereof, a fluorene, a carbazole, a dibenzosilole, and a dibenzogermole; and a polymer block (B) having as the monomer unit thereof a thiophene-2, 5-diyl group having a substituent group at least at the 3-position.
