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.
