A NEW SYNTHESIS OF ACENAPHTHOBENZOPORPHYRIN AND FLUORANTHOBENZOPORPHYRIN

摘要

Benzoporphyrins fused with acenaphthylene or fluoranthene(3)and(4)were prepared by the condensation of bicyclo[2.2.2]octadiene(BCOD)-fused tripyrrane(5)with appropriate pyrrole dialdehydes(13)or(14)and the subsequent retro Diels-Alder reaction.The absorptions of these new porphyrins were very intense at both Soret and Q bands,which might be useful as organic dyes for solar cells.
