Effective meso Fabrications of Subporphyrins

Effective meso Fabrications of Subporphyrins

A meso‐free subporphyrin was prepared and quantitatively converted into meso‐brominated subporphyrin, which is an effective precursor for the facile installation of substituents at the meso position. The meso‐(4‐amino)phenylethynyl subporphyrins (see picture; N blue, O red, Br orange, F pale green,...

Zusammenfassung:A meso‐free subporphyrin was prepared and quantitatively converted into meso‐brominated subporphyrin, which is an effective precursor for the facile installation of substituents at the meso position. The meso‐(4‐amino)phenylethynyl subporphyrins (see picture; N blue, O red, Br orange, F pale green, B dark green) and a butadiyne‐bridged dimer have split Soret‐like bands and red‐shifted and intensified fluorescence.
