Abstract:

Meso-hydroxyuroporphyrin I, B-hydroxypropionic acid uroporphyrin I, hydroxyacetic acid uroporphyrin I and peroxyacetic acid uroporphyrin I have been isolated from the urine and plasma of patients with congenital erythropoietic porphyria (CEP) by high-performance liquid chromatography and characterized by liquid secondary ion mass spectrometry and chemical properties. The physico-chemical properties of these compounds have been studied. The hydroxy- and peroxyacetic acid- uroporphyrin I derivatives are the true metabolites of uroporphyrinogen I in vivo and their presence in urine and plasma is

Abstract:

Les composés polymacrocycliques présentent un grand intérêt grâce à leurs caractéristiques remarquables de coordination. Pour la première fois, l’approche synthétique fonctionnelle aux diverses composés bi- et polycycliques contenant plusieurs fragments d’éthers aza-couronnes, aux cryptands et aux supercryptands à base d’éthers aza-couronnes a été élaborée par Krakowiak et ses collaborateurs au début des années 1990, par l’usage de simples réactions de substitution nucléophile. Actuellement, les composés hétéropolymorphes polymacrocycliques, capables de former des complexes polynucléaires avec

Abstract:

Twelve porphyrin dyads linked by an ethene bridge were synthesised as model systems for conjugated polymers. The extent of interporphyrin interaction was investigated for meso-meso and meso-β linked homo- and heterobimetallo-porphyrin dyads. To complement these dyads, model monomers with alkenyl substituents were also studied. Once the synthesis of these compounds was achieved, the extent of interaction was studied using UV-visible and fluorescence spectroscopy and molecular modelling. In order to gain a true indication of the extent of interaction in a dyad, the effect of the bridge a

Abstract:

Résumé : Le travail de recherche présenté dans ce mémoire fut inspiré par le processus de la photosynthèse qui se produit chez les plantes. Au cours de ce processus l’énergie solaire est convertie en énergie chimique via différentes étapes de transferts d’électrons et d’énergie. En maîtrisant bien ces concepts, de nombreuses applications, telles que les cellules photovoltaïques ou les DEL (Diodes électro-luminescentes) peuvent être améliorées. Pour se faire, il est important d’optimiser les propriétés des matériaux existants (oligomères, polymères, etc…) en préparant des systèmes conjugués plu
