Postdoctoral Research Scientist Position opened in the Department of Theoretical Chemistry at J. HeyrovskĂ˝ Institute of Physical Chemistry in Prague, Czech Academy of Sciences.
With support from the Czech Grant Agency (15-10279Y), Dr. Martin Srnec offers one postdoctoral fellowship for 2017. The project, based on the use of large-scale multireference ab initio, DFT and other theoretical methods, aims at calculations of redox properties of nonheme iron active sites and elucidation of their effects on reactivities and selectivities with respect to a possible design of new catalysts.
Iron as the most abundant redox-active metal in biology catalyzes many vital processes by performing difficult chemical reactions such as functionalization of aliphatic C-H bonds. In this proposal, we will focus on mononuclear and binuclear nonheme iron (NHFe) enzymes and their model complexes. These species are important not only due to their functions in nature but also represent challenging systems for both experimental and theoretical chemistry. From the theoretical point of view, the requirement for an accurate description of their complex electronic structures often complicates predictions of their redox potentials and related reactivities. Nowadays, a theoretical protocol that would be of great interest for the appealing possibility to reliably predict redox potentials and reactivities of important but experimentally elusive NHFe species is not yet available. Besides developing such a protocol, the results are expected to contribute to understanding of the general factors that control selective mechanisms in the realm of powerful NHFe enzymes and related bio-inspired complexes.
