Electronic spectra of pyrrolo[2,1-a]isoquinolines and pyrrolo[1,2-f]phenanthridines

The electronic absorption spectra of dioxo-compounds of the pyrroto[2,1-a]isoquinoline and pyrrolo[1,2-f]phenanthridine series and products of their condensation with o phenylenediamine were studied. The influence of substituents was demonstrated; halochromic phenomena in sulfuric acid medium were described; the fluorescence spectra are discussed.Institute of Technical Chemistry, Urals Branch of the Russian Academy of Sciences, Perm' 614600.
