Title:
HIGH-MOLECULAR-WEIGHT COMPOUND AND ORGANIC PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/047858
Kind Code:
A1
Abstract:
A high-molecular-weight compound containing a repeating unit represented by formula (A) and a repeating unit represented by formula (B) has a high absorption of light having a long wavelength and therefore can be used in an organic photoelectric conversion element and an organic thin-film transistor. [In formulae (A) and (B), R represents a hydrogen atom, a fluorine atom, an alkyl group which may be substituted, an alkoxy group which may be substituted by a fluorine atom, an aryl group, a heteroaryl group, a group represented by formula (2a), or a group represented by formula (2b), wherein multiple R's may be the same as or different from each other; and Ar1 and Ar2 independently represent a trivalent aromatic hydrocarbon group which has 6 to 60 carbon atoms and may have a substituent, or a trivalent heterocyclic group which has 4 to 60 carbon atoms.]
