Abstract: | Research activities in mass spectrometry were initiated in Mons in the mid-1960s when the first mass spectrometer was acquired by the laboratory of Organic Chemistry of the faculty of Sciences. Now, the Organic Synthesis and Mass Spectrometry laboratory (S2MOs) studies the following research themes:
- chemistry of natural molecules such as saponins, flavonoids, lipids and polysaccharides to (i) establish molecular diversity in living organisms such as plants, microalgae or marine animals to establish their biological role; (ii) modifying the structure of natural molecules to exacerbate their biological properties; (iii) using complex biological molecules to develop mass spectrometry techniques, particularly ion mobility spectrometry;
- chemistry of synthetic macromolecules such as biodegradable or conjugated polymers to essentially optimise MS methods for their structural characterisation or help our collaborators to validate their synthetic developments;
- chemistry of peptoids, which are synthetic biomimetic molecules of peptides to (i) establish the primary structure/secondary structure relationship and (ii) use the structural diversity linked to these molecules to create chiral selectors or systems able to store solar energy (Molecular Solar thermal Energy Storage - MOST);
- development of mass spectrometry methods for the analysis of original organic molecules, with a particular focus on ionisation/desorption, various ion activation techniques and ion mobility separation.
