Offer Description

Circularly-polarized luminescence (CPL) spectroscopy deals with chirality of the (emitting) excited state. In CPL, the electric field rotates constantly while lying on a plane perpendicular to its propagation direction, describing an either right- or left-handed helix. From practical viewpoint, the differential emission between right- and left- CPL arising from an electronic excited state in a chiral field, over the total emitted light, is quantified by the dissymmetry factor, g_Lum. To date, major efforts have been devoted to develop CPL-active organic systems,[1,2] yet their gLum values are typically unsatisfactorily low. On the other hand, phosphorescent Transition Metal Complexes (TMCs) possess appealing properties encompassing outstanding photo- and electro-chemical features, highly tunable emission color and relatively long-lived excited states.[3,4] Finally, lanthanide complexes are known to possess high values of dissymmetry factor.
Une of the tasks of the interdisciplinary project TORNADO aims at the synthesis, chiroptical and electrochemical characterisation of enantiopure d-metal complexes featuring metallophilic interactions.
The project is funded by the PEPR LuMa and involves a French consortium of 13 research laboratories, including 17 research groups and 2 characterisation platforms.

We are looking of a highly motivated candidate with a solid background in synthetic organic and/or organometallic chemistry and optical spectroscopy. The candidate must have earned a PhD (or equivalent) in Chemical Sciences or Molecular Chemistry with a chemical synthesis-oriented and spectroscopy background. He/she should be able to work with independence in a multidisciplinary environment and possess a curiosity-driven attitude. Very good knowledge of written and spoken communication skills in English is required. Knowledge of French is not essential.
The candidate must provide a letter of motivation, a detailed CV including the list of marks and the contact details of one (or two) reference(s).
