**Mission**:
Today, there is a strong need for research to improve the performance of propellants. Indeed, while the space industry, which is a major sector for the French economy, has long been protected, the field has become much more competitive due to the emergence of new players (China, SpaceX, etc.). It is therefore crucial to have systems that offer a better ratio of payload weight to total weight and therefore better operating and commercial costs.
The objective of this project, in partnership with CNES and ArianeGroup, is to design and develop new poly-nitrogen compounds for propulsion, called High Energy Density Materials (HEDMs), which would lead to specific impulse gains exceeding 30%. In particular, the laboratory is interested in the synthesis of extended analogues of hydrazines (triazanes, tetrazanes, pentazanes, etc.) or of the pentazolate anion.
The thesis will focus on the chemistry of polyazanes, the study of their reactivity and their development into HEDM derivatives by post-functionalization, notably using metals or light, in batch or flow conditions.
It will be carried out at the LHCEP in Villeurbanne. The LHCEP is a joint CNRS/University Claude Bernard Lyon 1/CNES/ArianeGroup unit, whose objective is to design and develop new polyazo compounds for propulsion. The postdoc will be part of the LHCEP team and will be able to rely on it. The unit has modern synthesis laboratories (Site de la Doua, Bâtiment Raulin, 5th floor) with all the equipment necessary for the study of these new compounds (flow reactors, DSC, calorimetric bomb, shock and friction sensitivity tests), as well as modeling workstations. Its core competence is in the chemistry of nitrogen-rich polyazo derivatives.
