The proposed project is aimed at advancing the fundamental knowledge of the synthesis and structure of homoleptic and heteroleptic metal-TEMPO complexes and their utilization to develop new reaction systems. Specific objectives include: i) development of a general non-redox synthesis of homo- and heteroleptic metal-TEMPO complexes, ii) analysis of the critical factors controlling the stability and structure of homoleptic and heteroleptic metal-TEMPO systems in photo-, thermo- and mechanochemically triggered conditions, iii) investigation on the reactivity of well-defined metal-TEMPO complexes toward model small molecules: CO2 and H2. The proposed investigations should provide a more in-depth mechanical understanding of the formation and reactivity of metal-TEMPO complexes in their initial and subsequent steps. Further studies involving CO2 and H2 should shed a light on the mechanism of their activation by metal-TEMPO systems, which may pave the way for developing novel well-defined stoichiometric and catalytic processes.

The responsibilities of the post-doctoral researcher will include:

• Development, synthesis (including mechanochemical and light-induced methods) and characterization of homo- and heteroleptic complexes with selected active metal centers supported by radical and anionic TEMPO.

• Investigation of small molecule activation and transformations on metal-TEMPO complexes.

• Characterization of physicochemical properties of the resulting complexes including following spectroscopic techniques IR, NMR, UV-Vis and basics of X-ray crystallography and SEM.

• Manuscript Preparation.

We offer a post-doctoral position (full-time employment) in the Institute of Physical Chemistry PAS with a gross salary of Around 9 650 PLN gross per month financed from the NCN OPUS 27 Project no 2024/53/B/ST4/02393 Entitled “Towards new chemistry of metal-TEMPO complexes as activators of CO2 and H2 molecules” 100% of the work time of Postdoc will be devoted to the realization of the proposed project.
