- Opis:
- Irradiation of cerium(IV) complex of octaethyl bisporphyrin Ce[OEP(-2]$\text{}_{2}$ with visible light, in the presence of CCl]$\text{}_{4}$ as an electron acceptor, leads to their photooxidation and π cation radical formation. The process was followed using electron absorption and magnetic circular dichroism spectroscopy. Electronic configuration in neutral mono- and bisporphyrin (sandwich) complexes were compared to the one of the neutral species. Photoirradiation of sandwich octaethyl- and tetraphenyl bisporphyrins, in the presence of an electron donor (triethylamine) results in their photoreduction on different pathways. Formation of the [Ce(III)(TPP)(-2)TPP(-2)]¯ and [Ce(III)(OEP)(-1)(OEP)(-2)] complexes was followed by absorption and electron spin resonance spectroscopy.
