Polymer compound and electric device

A polymer compound comprising a constituent unit represented by the formula (1) and a constituent unit represented by the formula (2):

• wherein R1 represents a hydrogen atom or a substituent;
• Y1 represents an oxygen atom, a sulfur atom or —N(R3)—;
• R3 represents a hydrogen atom or a substituent;
• ring Z1 and ring Z2 represent each independently an optionally substituted heterocyclic ring;
• wherein R2 is different from R1 and represents a hydrogen atom or a substituent;
• Y2 represents an oxygen atom, a sulfur atom or —N(R3)—;
• R3 represents a hydrogen atom or a substituent;
• ring Z3 and ring Z4 represent each independently an optionally substituted heterocyclic ring;
• and further comprising a constituent unit represented by the formula (3):
• —Ar1— (3)
• wherein Ar1 is a constituent unit represented by the formulae (3-2) or (3-8):
• in the formula (3-2), R23 and R24 represent each independently a hydrogen atom or a substituent with the proviso that at least one of R23 and R24 is a halogen atom;
• and in the formula (3-2) and (3-8), X21, X28 and X29 represent each independently a sulfur atom, an oxygen atom or a selenium atom.
