Porphyrins with Exocyclic Rings. Part 11. Synthesis and Characterization of Phenanthroporphyrins, a New Class of Modified Porphyrin Chromophores.

-Phenanthro[9,10-c]pyrroles (III) are prepared from nitrophenanthrene (I) and isocyanoacetic acid esters under Barton-Zard conditions. Compounds (III) are converted into porphyrins with one, two or four [cf.(IV)] fused phenanthrene rings using established procedures. This investigation is presented in connection with studies on the factors that influence the electronic spectra of extended conjugated porphyrin systems which are interesting for applications in medicine and material sciences. -(NOVAK,
