反応手順

1.0 g of 1,10-phenanthroline-5,6-dione in the Fourteen Preferred Embodiment was dissolved into 200 g of ethanol to prepare a solution. 1.0 g of o-phenylene diamine was dissolved into 100 ml of ethanol to prepare a solution. The latter solution was added into the former solution, and the mixed solution was current-circulated for 5 minutes. Then, the mixed solution was vacuum-concentrated to precipitate a crystal. The precipitated crystal was recrystallized by water-ethanol to obtain dipyrido (3,2-a:2',3'-c) phenazine. The melting point of dipyrido (3,2-a:2',3'-c) phenazine as the condensed polycyclic compound was 257° C. according to the DSC measurement.
