1. A polymer compound having a structural unit represented by formula (1): wherein X1 and X2 are the same or different and 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 or different and represent a hydrogen atom or a substituent; W1 represents a cyano group, a monovalent organic group having a fluorine atom or a halogen atom; and W2 represents a cyano group, a monovalent organic group having a fluorine atom, a halogen atom or a hydrogen atom;
and a structural unit represented by formula (D-1) wherein ring d represents an aromatic heterocyclic ring; m represents an integer of 1 or more; Z represents a group represented by formula (z-3), (z-4), (z-5), (z-7) and (z-8); when there are a plurality of rings d, they may be the same or different; when there a plurality of Zs, they may be the same or different: in formula (z-3), (z-4), (z-5), (z-7) and (z-8), R represents a hydrogen atom or a substituent; when there are a plurality of Rs, they may be the same or different; and Rs may bind to each other to aspect cyclic structure. |
