(Ar4TAPs) was developed. Ar4TAPs bearing various
substituents in meso-phenyls and anthracene residues
were prepared from the corresponding pyrrolic precursors. The synthesized
porphyrins possess high solubility and exhibit remarkably strong absorption
bands in the near-infrared region (790–950 nm). The scope of
the method, selection of the peripheral substituents, choice of the
metal, and their influence on the optical properties are discussed
together with the first X-ray crystallographic data for anthraporphyrin.
