Abstract
Provided is a polymer that suppresses dark current in a photoelectric conversion element. A polymer contains a structural unit having a main chain and a side chain, a weighted average of formula weights of the side chains weighted by a molar ratio of the structural units contained in the polymer is 160 or more, and an absorption edge intensity is 0.08 or less.
Claims19
A polymer comprising a structural unit having a main chain and a side chain, wherein
- a weighted average of formula weights of the side chains weighted by a molar ratio of the structural units contained in the polymer is 160 or more, and
- an absorption edge intensity is 0.08 or less.
A polymer comprising at least one selected from the group consisting of a structural unit represented by the following Formula (I) and a structural unit represented by the following Formula (Y1).
- (in Formula (I),
- Z1 is a group represented by the following Formula (Z-1), the following Formula (Z-2), the following Formula (Z-3), the following Formula (Z-4), the following Formula (Z-5), the following Formula (Z-6), or the following Formula (Z-7), and
- Ar1 and Ar2 each independently represent a trivalent aromatic hydrocarbon ring group or a trivalent heterocyclic group,
- in Formula (Y1), ArY1 represents an arylene group, a divalent heterocyclic group, or a divalent group in which an arylene group and a divalent heterocyclic group are bonded,
- in the groups represented by the following Formulas (Z-1) to (Z-7), at least one of R11 and R12 is a group represented by the following Formula (SC), and
- in Formula (SC), mSCA1 represents an integer of 1 or more and 10 or less, ArSC1 represents an arylene group, TSC represents an aryl group, and these groups optionally have a substituent.)
