Nitrogen-containing fused-ring compound, polymer comprising a nitrogen-containing fused-ring repeating unit, organic thin film, and organic thin film element

摘要

The present invention provides nitrogen-containing fused-ring compounds represented by the following formula (α-I):in formula (α-I), R²¹ and R²² each independently represent a hydrogen atom, a halogen atom or an optionally substituted monovalent group, and Z²¹ and Z²² each independently represent any one of the groups represented by the following formulas (α-i)-(α-ix);wherein R²³, R²⁴, R²⁵ and R²⁶ each independently represent a hydrogen atom, a halogen atom or a monovalent group, and R²³ and R²⁴ may bond together to form a ring, the left side and the right side of the group represented by formula (α-viii) may be interchanged.
