Excitation Process

Photoacoustic spectroscopy provides information about both amplitude and phase of the response of a system to an optical excitation process. This paper presents the studies of the phase in the electron transfer process between octaethylporphyn (OEP) and quinone molecules dispersed in a polymeric matrix. It was observed a tendency in the phase behavior to small values only in the spectral region near to 620 nm, while for shorter wavelength did not show any tendency. These measurements suggested that the electron transfer to acceptor occurred with the participation of octaethylporphyn singlet excited state.

Good combination! Axial coordination of gold porphyrin, as an electron acceptor, with zinc phthalocyanine, as an electron donor, results in the formation of a novel supramolecular dyad which can mimic the efficient electron transfer process of a photosynthetic reaction center complex.
