Photoinduced Charge Transfer in Molecular Materials Studied

Photoacoustic spectra of molecular materials based on the assembling of the [Fe(CN)6] molecular block were recorded and evaluated. Those compositions where the valence of the involved metals allows a charge transfer (an inner photoinduced redox reaction) through the CN ligand shown an intense photoa...

Sumario:Photoacoustic spectra of molecular materials based on the assembling of the [Fe(CN)6] molecular block were recorded and evaluated. Those compositions where the valence of the involved metals allows a charge transfer (an inner photoinduced redox reaction) through the CN ligand shown an intense photoacous tic signal around 600 nm; when this transition is unable only the signal corresponding to metal to ligand and d–d transitions within the metal were observed. This suggests that this technique provides a fast and reliable method to explore the existence of tunable photoinduced charge transfer in molecular materials.
