Post-doc in femtosecond XPS of bio-mimetic photoswitches (M/F)

In this joint collaboration between the Max-Born-Institute, Berlin (Dr. O. Kornilov) and the IPCMS Strasbourg (Dr. J. Léonard & Prof. S. Haacke), we bring together our expertise to investigate the CInt of rhodopsin-mimicking photo-switches using novel tools of femtosecond and attosecond XUV photoelectron spectroscopy (XUPS).

Application Deadline : 06 March 2023

Activities : Within a joint collaboration of the above partner labs, the post-doc position is located in both ultrafast spectroscopy labs in Strasbourg (Institut de physique et chimie des matériaux de Strasbourg) and at MBI, Berlin. The Strasbourg team has a long-standing experience with these particular, vibrationally coherent photo-switches , studied by broadband UV/VIS TAS with sub-10fs resolution . The team of Dr. O. Kornilov at MBI runs a state-of-the-art femtosecond UV-pump-HHG/XUPS-probe experiment with liquid jets . In recent experiments, the ground state XUPS spectra of the photo-switches were obtained, for both anionic and cationic forms with high photo-emission yield. The first pump-probe experiments are in progress at MBI.
The post-doc will complete the first proof-of-principle phase on well-characterised molecules, in Berlin, before the project is extended to new complexes aimed at studying the influence of vibrational coherence and chemical substitutions on the isomerisation quantum yield and dynamics at the CInt. This second phase implies experiments both in Strasbourg and Berlin, relying on the above set-ups. Theoretical support will be provided by Prof. M. Olivucci (U Siena & Bowling Green), inventor of the photo-switches, and Dr. S. Gozem (GSU Atlanta). Photo-switches will be designed for this project and provided in sufficient amount by chemistry partners. Some of them are commercially available.

Skills : The candidate should posess good knowledge in molecular physics and/or physical chemistry and have to be ready to utilize novel non-standard experimental methods and perform advanced data analysis.
The post-doc, since in an early stage of his career, is encouraged to pursue new ideas, publish first-class papers and present his work at conferences, mentor graduate students, and contribute to fund raising.
