Ultrafast coherent photoisomerization in biomimetic photoswitches

Date Do, 29.11.2012 - Do, 29.11.2012
Time 10.15
Speaker Dr. Jérémie Léonard, Institut de Physique et Chimie des Matériaux, IPCMS-DON, Université de Strasbourg - CNRS, France

Program Within the Department of ultrafast Optics and Nanophotonics (DON) at IPCMS, the BIODYN team (for « BIOmolecular DYNamics ») applies femtosecond spectroscopy to investigate photoinduced ultrafast processes in organic molecules in condensed phase. After introducing shortly our different subjects of interest (organic photovoltaics, biomolecular interactions), I will focus on our latest work on ultrafast coherent photoisomerization in biomimetic photoswitches. Coherent photoisomerization is a rare, ultrafast process in which the photon energy activates a selected set of reactive vibrational modes, thus ensuring efficient photomechanical energy conversion. We combine experimental and theoretical approaches to investigate this process in a model molecular switch. Transient absorption reveals signatures of a quantum vibrational wave packet that drives the molecular motion from the electronic excited S1 to the ground S0 states, thus mimicking energy conversion in rhodopsin. Quantum chemistry and semi-classical trajectory computations allow us to unravel the mechanistic origin of the observed oscillations.
