Hussein, Hiba. "Synthèses de nouveaux ligands carbènes à structures N-hétérocycliques et macro-N-Bis-hétérocycliques symétriques et dissymétriques. Études de leurs propriétés photophysiques, biologiques et de coordination". Electronic Thesis or Diss., Université de Lorraine, 2022. http://www.theses.fr/2022LORR0014.
Texto completoThe objective of this thesis is to prepare new photosensitive molecules of N-heterocyclic carbenes, ligands or complexes, designed to meet the criteria of photosensitizers (PS) (pure, water-soluble, biocompatible, non-toxic molecules, with maximum absorbance efficiency, possessing good photophysical properties) applicable in the field of materials and/or in the biomedical field such as phototherapy. The ambition is to optimise the spectroscopic properties of the photosensitisers and to obtain a good photoactivity. This thesis describes in a first chapter a non-exhaustive state of the art concerning heterocyclic macrocycles, N-heterocyclic carbenes (NHC) and NHC macrocycles as well as a reminder of the expected properties of photosensitive molecules. In a second chapter, it details the syntheses of original N-heterocyclic and N-bis-heterocyclic bis-imidazolium ligands of open or closed macrocyclic structures as well as their physicochemical characterizations (infrared, NMR, mass spectroscopy). Crystallographic structures of some of these macrocycles were obtained by X-ray diffraction. In a third and final chapter, the various tests for the formation of carbenes and the study of their complexation properties towards transition metals are detailed. Theoretical Gaussian calculations are used to support this study. A fluorescence and singlet oxygen production study as well as an evaluation of the biological properties of the previously presented flexible macrocycles and ligands show promising photophysical and biological properties. In addition, an interesting preliminary study of the proton/deuterium exchange of carbon protons of bis-imidazolium macrocycles is described.Keywords: NHC, macrocyclic ligands, bipyridine, bithiazole, imidazolium, photosensitiser, photoactivity, anti-bacterial properties

Texto completo: Recent developments in green and sustainable science require more powerful, sophisticated and tunable catalysts. Bimetallic catalysts contain two or more sites for the activation of substrates and, under optimal circumstances, can allow cooperative activation of reacting substrates on neighboring metal centers. A number of backbones, designed specifically to generate exclusively bimetallic complexes have previously been developed around methanodibenzodioxocin and benzofurobenzofuran scaffolds, including a number of ligands that act as monophosphine donors to two different metal centers. These ligands generate dinuclear species reliably, but the resulting coordination modes are unpredictable. This work presents the synthesis of tetraphosphine ligands, wherein chelating arms are available to coordinate each of the two metal centers. The synthesis involves preparation of 4,8-bis(sec-phosphines) of rac- 6,12-methano-12H-dibenzo[l,3] dioxocins and their conversion into doubly chelating phosphines through the elaboration of each sec- phosphine functionality into the corresponding di(R)phosphinopropyl derivatives (R= Ph, Cy). A preliminary coordination chemistry study indicates that the tightly defined coordination environment provided by these rigid binucleating tetraphosphine ligands under study allowed bimetallic complexes of PdII, PtII to be prepared, in which each of the two chelating arms molecule coordinates to one metal. Finally outline studies on the use of the tetraphosphine ligands as supports for hydroformylation chemistry were performed. The current results do not yet allow cooperative behavior between the two metal centers to be definitively established
