Abstract:

Novel photoactive ruthenium(II) complexes were designed to incorporate existing anti-tuberculosis drugs, isoniazid and nicotinamide, that could be released from the ruthenium(II) cage by photoactivation with visible light. Two sets of complexes were synthesised based on cis-[Ru(N-N')2(L)2][PF6]2and cis-[Ru(N-N')2(L)X][PF6], where N-N' is 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen), L is isoniazid (INH) or nicotinamide (NA) and X is either Cl or I. Their dynamic behaviour in solution was explored using NMR to probe the presence of atropisomers. In the case of cis-[Ru(bpy)2(NA)Cl][PF6] (

Abstract:

An experimental approach was taken in determining the quantum yield of Ruthenium(II) with Oxygen using two different Ru complexes. This reaction results in Ruthenium(III) and O2-. The Coulombic interactions caused by a carboxylate functional was found to increase the yield of charge separation. This was done using a diode to measure the intensity of the completed reaction over a certain time frame. The intensities were turned into concentrations. The concentration over time was used to determine the quantum yield. This information is useful in creating more efficient light emitting diodes.

Abstract:

Application of chemotherapeutic agents in current cancer treatment has been limited by adverse effects as poor selectivity results in systemic toxicity; most chemotherapy approaches also experience inherited or acquired drug resistance which lead to reduced treatment outcome.

Abstract:

According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of ultra-pure silicon, and therefore the computing power, will double every 18 to 24 months. However, around 2020 hardware manufacturers will have reached the physical limits of silicon. A proposed solution to this dilemma is molecular electronics. Within this field researchers are attempting to develop individual organic molecules and metal complexes that can act as molecular equivalents of electronic components such as wires, diodes, transistors and capacitors.

Abstract:

Ce travail s'inscrit dans le cadre général de la mise au point et de l'étude d'agents potentiellement photothérapeutiques. Dans cette optique, les recherches menées dans notre laboratoire sont consacrées principalement à l'étude de complexes photooxydants de ruthénium(II) contenant des ligands &61552;-déficients TAP (1,4,5,8-tétraazaphénanthrène). Ces composés sont en effet capables, sous illumination, d'oxyder différentes biomolécules pour mener, notamment, à la formation de photoadduits qui pourraient perturber le fonctionnement d'enzymes cellulaires in vivo.<p><p>La première partie de ce tr

A l’Université Libre de Bruxelles, les complexes polyazaaromatiques du Ru(II) sont synthétisés et étudiés dans le cadre du développement d’outils de diagnostic de l’ADN, de drogues photo-activables, de nouveaux matériaux opto-électroniques … Certains de ces complexes possèdent une importante photoréactivité vis à vis de l’ADN ;elle résulte d’un transfert d’électron photo-induit entre une guanine, jouant le rôle de donneur, et le complexe dans un état excité 3MLCT. La photo-oxydation des acides aminés tryptophane et tyrosine a également été observée. La photo-oxydation de cibles biologiques peu

Abstract:

The goal of this research was to develop a series of mixed-metal supramolecular complexes through systematic component variation to better understand the role of structural modification on basic chemical and photochemical properties including photocatalysis of H₂O to H₂. Varying bidentate polypyridyl terminal ligands (TL), non-chromophoric halides (X), or number of Ru(II) light absorbers (LA) tunes the electrochemical, spectroscopic, photophysical, and photochemical properties within the supramolecular architecture. Ru(II),Rh(III),Ru(II) trimetallics of the design [{(TL)₂Ru(dpp)}₂RhX₂](PF₆)₅ (

Abstract:

This dissertation describes the design and synthesis of a series of half-sandwich amino acid complexes of the form), (aa = α-amino carboxylate), and their utility as asymmetric transfer hydrogenation catalysts of ketones. Variation of the metal center, the n-ring, and the aa was used to tune these systems for specific sets of ketones. Upon reaction with homochiral]s, the ligand environment in all of these complexes is pseudotetrahedral, leading to stereogenic metal ions (SM, RM). The addition of another stereogenic center from the amino acid ligand (the carbon, RC or SC;glycine) gives rise to
