Abstract
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,…
