Indaphyrin, a meso-tetraphenylsecochlorin-derived chromophore incorporating o-phenyl-to-β-linkages

McCarthy, Jason R.,Hyland, Michael A.,Brueckner, Christian

, p. 1738 - 1739 (2003)

Acid-induced cyclization of meso-tetraphenyl-2,3-secochlorin-2,3-dialdehyde produced meso-diphenylindaphyrin, a novel secochlorin-based chromophore in which linkages between the o-phenyl and the β-position force the mesophenyl groups into co-planarity with the porphyrinic π-system.
