Description of the thesis topic
The photoredox catalysis is now considered as a very important topic in the field of organic synthesis. Indeed, due to the mild reaction conditions bring by visible light many different reactions are now accessible through this concept simply by using the appropriate photocatalyst. To go further, heterogenization of the photocatalyst appears to be a valuable solution to recycle the photocatalyst and reach sustainable processes. Rapid and efficient synthesis of supported photocatalyst is still a remaining challenge and the choice of the support material is crucial. Thanks to their stability and versatility, polymer supports seems to be interesting alternatives to inorganic porous materials (zeolites, MOF…). The present project aims at preparing a new generation of precisely shaped porous polymer supports embedding non-toxic organic dyes. Precise shaping of the support in the form of monoliths or particles are made possible by 3D printing and photopolymerization. Then the performances of these news heterogeneous photocatalysts will be evaluated in organic transformations.
This project combines the competences of IS2M in photopolymerization and LIMA in heterogeneous photocatalysis. The candidate will work in both laboratories located on the same campus (Illberg campus, Mulhouse).
The Mulhouse Materials Science Institute (IS2M) is a CNRS-University mixed research unit located in Haute-Alsace (UMR 7361). Because of its multidisciplinary character, its scientific impact and the way it interacts with other fields, the laboratory represents one of the structuring forces in the field of Materials and their applications in the academic and industrial world, both at regional and national level. The IS2M has been able to define its identity and acquire unquestionable visibility on the highly competitive landscape of international research.
The LIMA laboratory (Laboratoire d'Innovation Moléculaire et Applications) is a three-tiered mixed unit, CNRS-UHA-Unistra which is localized both in Mulhouse and Strasbourg. The laboratory is organized in 10 research teams and gather more than 90 collaborators staff specialized in molecular chemistry. The LIMA is a major actor in the field of organic chemistry from fundamental science to more applicated. The laboratory is world recognized for its work on synthetic reactions developments and their applications in the fields of life science, catalysis, environment, and materials.
The PhD will be attached to the Doctoral School of Chemical Sciences University of Upper Alsace (ED222).
Constraints and risks
Laser risks (class 4)
The candidate should have a strong background in synthesis and characterization of polymers. Background and skills in organic synthesis will be appreciated. The pluridisciplinary and collaborative context of this project requires that the candidate has a strong motivation, curiosity to expand his/her area of expertise, autonomy and ability to work in a team.
The PhD student will benefit from a double formation in polymer science and organic synthesis and will develop his/her communication skills through oral presentations, writing articles, participation to conferences.
Applications should include a detailed CV (including referees able to be contacted), a letter of motivation, as well as all grades of Engineer school or Masters Degree.
