Texte intégralThe development of a novel class of multifunctional POM hybrids, denoted as ″SiW10-B10-Organic ligand" starting from the POM-Borate precursor ″SiW10-monoB10", has been investigated for biological applications. The latter resulted from the reaction of the carbonyl group of closo-decahydrodecaborate anion [B10H9CO]- with one of the two pendant amine groups of the organic linker 3-(Aminopropyl)triethoxysilane (APTES), which is covalently attached to the POM Keggin-type polyoxometalate [SiW10O36]2-.Herein, we aimed to go further by functionalizing the second amine function of SiW10-monoB10.The mono-adduct ″SiW10-monoB10” compound was firstly synthesized with good purity and in sufficient quantities, then characterized by atypical 1H-15N HMQC NMR, which allowed the examination of the nature of the free amine function and showed the presence of non-zero amine fraction that would not be involved in the H-H interaction with the decaborate cluster. Consequently, the possibility of new functional groups on this free amino arm of SiW10-monoB10 adduct was tested and followed through 1H and 11B NMR. Despite our best efforts and the various strategies, we have investigated, the studies carried out show that interactions with the POM part and with B-H groups are preferential to the formation of the covalent bonds we had hoped for.In the following section, we turned our attention to other hybrid POMs used as photoinitiators. Anthracene-, benzophenone- and anthraquinone-based derivatives were respectively covalently grafted onto the polyoxometalate (POM) platform [Mo6O19]2-, giving rise to highly colored organo-imido Lindqvist complexes: POM-imidoanthraquinone (POM-AQ), POM-imidoanthracene (POM-AC), and POM-imidobenzophenone (POM-AB). It has been evidenced that photosystems combining N-methyldiethanolamine (MDEA) as electron donor and these hybrid POMs promote free-radical photopolymerization of acrylate monomer derivatives under irradiation in the visible range, while in similar conditions, no polymerization was observed considering when adding each of the hexamolybdate cluster or the organic entity alone with the MDEA and acrylate monomers. Such organo-imido Lindqvist species can represent new, easy-to-synthesize, efficient visible-light photoinitiators. Moreover, due to the presence of the POM, coatings prepared using the POM-AQ/MDEA/Soybean oil epoxidized acrylate photosystem exhibit excellent mechanical properties, with very good flexibility, resistance to brittle fracture, and adherence to the steel.In the last chapter, the preparation of new closo-borate/CD inclusion complexes has been studied to elaborate systems strong enough to be considered for biological application. Playing on the volume and charge of [B10H10]2- was set out to increase their chaotropic character and thus enhance their binding affinity to cyclodextrins. The encapsulation of [B10H9NCCH3]- and [B20H18]2- anions within cyclodextrins has been investigated in two different parts. ESI-MS and NMR evidenced the formation of inclusion complexes between the borate compounds and beta- and gamma-CDs, while weaker interactions are evidenced with alpha-CD, for which the binding constants were determined by NMR and ITC. These constant values are much higher than those obtained in previous work with [B10H10]2- thus validating the approach followed in this thesis work.A new approach in [B20H18]2- chemistry has also been studied at the end of the work related to the Hydrogen-Deuterium exchange process in [B20H18]2- aqueous solution.1H{11B} and 11B{1H} NMR evidenced selective deuterium-proton exchange processes with the protons of equatorial Boron atoms over a period of time with the presence of degradation. Interestingly, it has been shown through NMR of [B20H18]2-/CD solutions in D2O that beta- and gamma-CDs would protect the anion from degradation after 4-5 months, opening the route for designing Boron-based drugs with enhanced stability suitable for medical use
