The visible and near ultraviolet absorption spectra have been measured for thin films of H2Pc [C32H18N8], MgPc, FePc, CoPc, CuPc, and ZnPc. Magnesium and iron phthalocyanine have very different absorption spectra. For most of the phthalocyanines, structure of magnitude 0.21 eV is seen on the visible and Soret bands. A d band is indicated in the region 4.0–4.7 eV. This is the spectral region most sensitive to substitutions of the central metal atom.
