HIGH-MOLECULAR-WEIGHT COMPOUND AND ORGANIC PHOTOELECTRIC CONVERSION ELEMENT

摘要

A high-molecular-weight compound comprising a repeating unit represented by formula (A) and a repeating unit represented by formula (B), which has high absorption of light having a long wavelength and is useful for an organic photoelectric conversion element. [In the formula, X1 and X2 are the same as or different from each other and independently represent a nitrogen atom or =CH-; Y1 represents a sulfur atom, an oxygen atom, a selenium atom, -N(R1)- or -CR2=CR3-; R1, R2 and R3 are the same as or different from one another and independently represent a hydrogen atom or a substituent; W1 represents a monovalent organic group having a fluorine atom, a cyano group or a halogen atom; W2 represents a monovalent organic group having a fluorine atom, a cyano group, a halogen atom or a hydrogen atom; and Q and R are the same as or different from each other and independently represent a hydrogen atom, a fluorine atom, an alkyl group which may be substituted by a fluorine atom, an alkoxy group which may be substituted by a fluorine atom, an aryl group which may be substituted, a heteroaryl group, or a group represented by formula (2).]
