Abstract

ir - anions of metalloporphyrins attract special attention due to the important role metalloporphyrins play in the redox processes in biology. The porphyrin ir - anions are known to be short-lived intermediates of photoreduction reactions. As the anions produced by alkalimetal reduction in aprotic solvent are stable products, their properties are investigated by various spectroscopic methods. However there are no data available on the photophysical processes of ir - anions. Information about the properties of excited states is undoubtedly nesessary for the description of a complete picture of ir - anions photochernistry. In this paper the photophysical processes in Zn-octaethylporphin and Zn-octaethylphlorin ir - monoanions (P and PH- , structural formulas I and II, respectively, Fig. 1) are investigated by picosecond absorption spectroscopy. The phiorin anions can be treated as a protonated species of porphyrin ir - dianions: P2 +H+ PH-.
