Conjugated compound, nitrogenated condensed-ring compound, nitrogenated condensed-ring polymer, organic thin film, and organic thin film element

摘要

According to the first invention group there are provided conjugated compounds having two or more groups represented by the following formula (I) or the following formula (II):; wherein one of Ar and Ar′ represents a C6 or greater divalent aromatic hydrocarbon group and the other represents a C4 or greater divalent heterocyclic group, wherein the groups each may have a substituent, with the proviso that the groups as a whole contain no fluorine atoms, R¹ and R² each independently represent a hydrogen atom, a halogen atom or a monovalent group, and Ar″ represents a trivalent aromatic hydrocarbon or trivalent heterocyclic group; when the conjugated compound has two or more groups represented by formula (I), the portion excluding these groups contain no fluorine atoms.;According to the second group of the present invention there are provided 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.
