NITROGEN-CONTAINING CONDENSED RING COMPOUND, NITROGEN-CONTAINING CONDENSED RING POLYMER, ORGANIC THIN FILM, AND ORGANIC THIN FILM ELEMENT

摘要

It is an object of the present invention to provide a nitrogen-containing condensed ring compound, which can be used as an organic n-type semiconductor having an excellent electron transport property and which is also excellent in terms of solubility in an organic solvent. The nitrogen-containing condensed ring compound of the present invention has a structural unit represented by the following formula (1-1) or formula (1-2): wherein Ar1 represents an aromatic ring; one of Y1 and Y2 represents a single bond, and the other represents—C(R11)(R12)—or—C(═X1)—; one of Y3 and Y4 represents a single bond, and) the other represents—C(R21)(R22)—or—C(═X2)—, and one of Y1 to Y4 represents—C(R11)(R12)—or—C(R21)(R22)—; at least one of W1 and W2 represents—N═; and Z1 and Z2 each represent any one of the groups represented by the formula (i) to the formula (ix).
