Insight into the rules dictating the formation of arene ruthenium metalla-assemblies

Garci, Amine ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

The self-assembly process is a natural phenomenon with the ability to organize biological systems. Its development by chemists as a synthetic process allowed the formation of esthetical structures as well as highly complex supramolecular systems with remarkable biological functions. Since 1990, metal directed self-assembly strategy has largely contributed to the design and synthesis of discrete...

Complexes arène-ruthénium multinucléaires fluctuants : véhicules pour le transport intracellulaire de molécules cytotoxiques et photosensibilisantes

Freudenreich, Julien ; Süss-Fink, Georg (Dir.) ; Therrien, Bruno (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2012.

Depuis plusieurs années, la thérapie photo-dynamique est pratiquée au quotidien pour soigner certaines tumeurs, comme le mélanome. La méthode consiste à traiter le patient au moyen d’un composé photosensible, indifféremment absorbé par les cellules normales et cancéreuses, ces dernières le retenant toutefois plus longtemps. Après plusieurs heures, le composé est activé par une...

Ru2(CO)4{OOC(CH2)nCH3}2L2 sawhorse-type complexes containing μ2-η2-carboxylato ligands derived from saturated fatty acids

Johnpeter, J. P. ; Therrien, Bruno

In: Journal of Structural Chemistry, 2011, vol. 52, no. 1, p. 151-159

The thermal reaction of Ru3(CO)12 with the saturated fatty acids (heptanoic, nonanoic, decanoic, tridecanoic, tetradecanoic, heptadecanoic, octadecanoic) in refluxing tetrahydrofuran, followed by addition of triphenylphosphine (PPh3) or pyridine (C5H5N), gives the dinuclear complexes...

Arene Ruthenium Assemblies for Biological Applications : From Carceplex to Host-Guest Metalla-Cages

Barry, Nicolas ; Süss-Fink, Georg (Dir.) ; Therrien, Bruno (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2011 ; 2192.

Since the development of supramolecular chemistry in the 1980s more and more discrete molecular objects have been synthesised. In this research area metals play a key role. Indeed, the coordination-driven self-assembly allows a directional-bonding approach that organises the different building blocks into supramolecular objects according to the coordination modes of the transition metal....
