Abstract
Official abstract text for this publication.
Compound comprising structural units represented by formula (1) and formula (2): wherein X 1 , X 2 , X 3 and X 4 are the same or mutually different and represent a nitrogen atom or ═CH—; Y 1 and Y 2 are the same or mutually different and represent a sulfur atom, an oxygen atom, a selenium atom, —N(R 1 )— or —CR 2 ═CR 3 —; R 1 , R 2 and R 3 are the same or mutually different and represent a hydrogen atom, a halogen atom, an amino group, a cyano group or a monovalent organic group; W 1 and W 3 are the same or mutually different and represent a halogen atom, a cyano group or a monovalent organic group; W 2 and W 4 are the same or mutually different and represent a hydrogen atom, a halogen atom, a cyano group or a monovalent organic group. The structural unit represented by formula (1) and the structural unit represented by formula (2) are not the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A photoelectric conversion device comprising a first electrode and a second electrode and comprising an active layer between the first electrode and the second electrode, wherein the active layer comprises a polymer compound comprising a structural unit represented by the formula (1) and a structural unit represented by the formula (2): wherein X 1 , X 2 , X 3 and X 4 represent a nitrogen atom, Y i represents an oxygen atom; Y 2 represents a sulfur atom; W 2 and W 3 are the same or mutually different and represent a halogen atom, a cyano group or a monovalent organic group; W 2 and W 4 are the same or mutually different and represent a hydrogen atom, a halogen atom, a cyano group or a monovalent organic group; and the structural unit represented by the formula (1) and the structural unit represented by the formula (2) are not the same; and further comprising a structural unit represented by the following formula: wherein R represents a hydrogen atom, a halogen atom, an amino group, a cyano group or a monovalent organic group, the two R may be the same or mutually different, and two R may be mutually linked to form a cyclic structure together with carbon atoms to which they are linked. 2. The photoelectric conversion device according to claim 1 , wherein W 1 , W 2 , W 3 and W 4 are all a halogen atom. 3. The photoelectric conversion device according to claim 1 , wherein the polymer compound has a polystyrene-equivalent weight-average molecular weight of 3×10 3 g/mol or more.
