Article abstract of DOI:10.1246/bcsj.54.937

New annelated 5-amino-1,4-diazaanthraquinones and related derivatives were prepared from 2,3,5-triamino-1,4-naphthoquinone or 5-amino-2,3-dichloro-1,4-naphthoquinone.Their visible absorption spectra were examined by the PPP-SCF-MO calculation with a varia
