文摘

Porphyrin derivatives are known to have absorption spectra in the visible region (400-700 nm). In the present Letter, a new (to the best of our knowledge) broad band is reported in the NIR region (700-900 nm) of the absorption spectra of zinc tetraphenylporphyrin, zinc octaethylporphyrin and magnesium octaethylporphyrin in aromatic solvents at high concentrations (鈭?0^鈭? mol/L). The broad absorption band in the NIR region is ascribed to be due to ground state charge transfer complex formation between the presently used metalloporphyrins and aromatic solvents.
