Real-Time Probing of Fast Photoinduced Charge-Transfer in Electron Donor-Acceptor Model Compounds and in Biological Photosensors

Martin M. M., Plaza P., Changenet-Barret P.

Polish Journal of Chemistry

2008

Vol. 82, nr 4

759-771

We review some of our results on the role of solvent reorganization as an actual reaction coordinate in a few photoinduced charge-transfer processes concerning: dimethylaminobenzonitrile (DMABN), bianthryl and its 10-cyano-derivative and anthracenedimethylaniline (ADMA), in solution at room temperature. These processes were studied by subpicosecond transient absorption spectroscopy. We also describe some of our recent results on charge-transfer processes involved in the primary response of photoactive proteins such as the photoactive yellow protein (PYP) and the oxyblepharismin-binding protein (OBIP). The deciding role of the protein environment in the photophysics of the chromophore is emphasized.

Real-time probing of elementary charge transfer processes in liquids and solutions

Gauduel Y.

Bulletin of the Polish Academy of Sciences. Chemistry

1999

Vol. 47, No. 4

303-331

With the intensive development of ultrafast spectroscopic methods, the course of elementary reactions may be observable on the time scale of molecular motions. The : femtosecond solution chemistry allows the real-time probing of solvent cage effects during charge transfers. Recent studies devoted to the understanding of electron dynamics in : liquid phase are presented and discussed in the framework of quantum theories on nonequilibrium electronic states. This progress provides guidance for further research works on the microscopic description of reactional processes occurring in complicated many body systems.
