ORGANIC PHOTOELECTRIC CONVERSION ELEMENT

摘要

The purpose of the present invention is to provide an organic photoelectric conversion element which has excellent durability. The present invention provides an organic photoelectric conversion element which contains a conjugated polymer compound that has a partial structure represented by chemical formula (1). (In the formula, X represents O, S, NR2 or CR3=CR4; W represents CH or N; L represents a linear or branched alkylene group having 1-10 carbon atoms; each of Y1 and Y2 represents O or NR5; Z represents C, S or P; each of R1-R5 represents H, a linear or branched alkyl group having 1-24 carbon atoms, a cycloalkyl group having 3-20 carbon atoms, an alkenyl group having 2-20 carbon atoms, an aryl group having 6-30 carbon atoms or a heteroaryl group having 1-20 carbon atoms; and a, b and c represent integers satisfying 3 <= a + b + c <= 4 and 0 <= a, b, c <= 2.)
