Abstract

The iron and cobalt phthalocyanines included in the title have been synthesized. Their absorption spectra are unusual compared to other metallophthalocyanines, showing intense hypochromism in the Q band region. The cobalt and iron derivatives show 4-electron reduction capability in the electroreduction of oxygen over the entire range of pH values and in neutral and alkaline pH, respectively, although the potentials are not necessarily positive enough.
