18 months starting September 2020

Post-doctoral position in organic chemistry/photo-bio-chemistry

Filled

Over the last decade, photothermal therapy (PTT) have attracted increasing attention as a potential alternative to classical ones. It involves both molecules or nanoparticles absorbing photons upon NIR irradiation and generating heat through non-radiative relaxation pathways.

In this context, applications are open for a postdoctoral fellowship position funded by the “FireLight” projet-FEDER – Photoactive molecules and nanoparticles. The position will be based at L2CM laboratory in Nancy (France). The research program will focus on the synthesis of calixarene derivatives and the characterization of the optical and photophysical properties of the resulting molecular self-assemblies and calixarene-MoS2 nanoparticles assembled systems. The project will also include photobiochemical characterization triggering anti-bacterial applications.

Skills/Qualifications: Candidates for this postdoctoral fellowship must hold a PhD degree in organic chemistry, preferably with experience in photobiochemistry. Creativity, autonomy and strong reliability are highly required. All applicants must be able to communicate fluently in French and/or English (speaking and writing). The position is available for a period of 18 months, starting from September 2020.

Selection process: Interested candidates should send a CV, a scientific track record, a motivation letter and two recommendation letters to:

Prof. Jean-Bernard Regnouf de Vains / Prof. Andreea Pasc

PhD position: Photoactive Iron Complexes: Design and Application to Solar Energy

Filled

The aim of the thesis program is to develop photosensitive compounds from low-cost and environmentally friendly metal complexes. While ruthenium complexes have been widely studied and used in many laboratory applications because of their ideal photophysical properties, ruthenium is a rare, toxic and expensive metal, which limits real industrial development. Our project aims to replace this metal with other metals such as iron, which is strategic in the search for low-cost devices and industrial processes that conserve resources. In particular, we are targeting the development of photosensitizers for the manufacture of dye solar cells (DSSCs).

PhD project: Study and development of polar organometallic tools: towards the preparation and selective functionalization of heterocycles

Filled

The synthesis of (hetero)aromatic compounds is an omnipresent challenge for the organic chemist due to their multiple and varied applications. Indeed aromatic and heterocycle moieties are everywhere in day life, either in materials science, optics, electronics or biology. Thus, researches in organic synthesis methodologies are continually in progress for the preparation of heterocycles and their functionalization.

That is why, the aim of this PhD project is to develop original organometallic reagents to allow the development of innovative synthetic sequences for the preparation of highly functionalized (hetero)aromatic derivatives. In particular, we will focus our attention on bimetallic ate complexes as metalating reagents for metal-halogen exchange (MHE) or deprotonation. Their design, preparation and reactivity will be studied at first on heterocycle model and then exemplify to various heterocycles. Bimetallic ate complexes result in combining a polar organometallic (e.g. an organolithium) with a “soft” organometallic (organomagnesium for example), which the behaviour is different from those of the precursor. The principle is a synergy created by mixing two different organometallic reagents allowing increased selectivity and reactivity as well as use under non-cryogenic conditions compared to the monometallic reagent.
