| abstract |
The present invention provides nitrogen-containing fused-ring compounds represented by the following formula (α-I):n nin formula (α-I), R 21 and R 22 each independently represent a hydrogen atom, a halogen atom or an optionally substituted monovalent group, and Z 21 and Z 22 each independently represent any one of the groups represented by the following formulas (α-i)-(α-ix);n nwherein R 23 , R 24 , R 25 and R 26 each independently represent a hydrogen atom, a halogen atom or a monovalent group, and R 23 and R 24 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. |
