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

摘要

The present invention provides a nitrogen-containing fused ring compound having the structural unit of at least one member selected from the group consisting of structural units of the formula and the structural unit (1-2) of the formula (1-1). [{The formulas, Ar ¹ represents an aromatic ring having 4 or more carbon atoms which may have a substituent, Y ¹ and Y ² Any one of -C (= X ¹⁾ - represents a group of, the other represents a single bond, Y ³ and Y ⁴ Any one of -C (= X ²⁾ - represents a group of, the other represents a single bond, X ¹ and X ² are independently O, S or C = (A ¹⁾₂ of the group (A ¹ are each H, represents a halogen or a monovalent, two a ¹ is which may be the same or different from each other) an represents, Z ¹ and Z ² are groups each independently O, S, Se, Te, formula (a-1) , represent the formula (a-2) a group of formula (a-3) group, the formula (a-4) group or a group of formula (a-5)} of the {Expression of that, R ³ to R ⁶ are independently H, halogen, or represents a monovalent group, R ³ and R ⁴ are bonded to each other to form a ring, respectively};
