Subject Area
Organic Molecular Chemistry - Synthesis and Characterisation
Term
since 2020
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 433136929
In this project we will investigate the special features of photoredox active Cu-complexes as catalysts in visible light mediated processes based on the hypothesis that inner sphere mechanisms beyond electron transfer are involved as opposed to widely applied ruthenium and iridium based catalysts. We will develop mononuclear copper (I) and copper(II) complexes that will allow the photocatalytic generation of radicals or carbanions stabilized as organoCu(II) and organoCu(III) intermediates. Such intermediates would open new avenues in organocopper chemistry, which is currently dominated by organocopper(I) compounds. The central aim of the project is to develop new copper(I) and copper(II) complexes with extended excited life times and strong reduction or oxidation potentials and to deduce the mechanisms of their mode of action in light induced ATRA-type processes. An integrated approach of organic and organometallic synthesis and coordination chemistry (Oliver Reiser, OR), spectroscopy and theory (Julia Rehbein, JR) will be followed, which will be further complemented by collaborations in the areas of ps-TRIR (Patrick Nürnberger, Physical Chemistry, University of Regensburg), adsorption and emission spectra a variable temperatures down to 1.5 K (Rafal Czerwieniec, Physical Chemistry, University of Regensburg) and XAS spectroscopy (Michael Rübhausen, CFEL, Hamburg).
