Thèse de doctorat : Université de Neuchâtel, 2012 ; 2256.

The aim of this thesis is to combine metals and dendrimers to obtain mesomorphic or biological properties. The design of metamaterials from gold nanoparticles is still a challenge as the spatial organisation is difficult to control. Thus, the combination of gold nanoparticles with liquid-crystalline dendrimers is a way to explore the organisation of such systems in mesophases. We...

Metallic ruthenium nanoparticles derived from arene ruthenium complexes : synthesis, characterization and applications

Khan, Farooq-Ahmad ; Süss-Fink, Georg (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2012 ; 2247.

The present work deals with the preparation of ruthenium nanoparticles using an organometallic approach. In the first part, the synthesis of ruthenium nanoparticles stabilized by mesogenic isonicotinic ester ligands is presented. We have been interested in the use of long-chain isonicotinic esters as lipohilic components in order to increase the anticancer activity of arene ruthenium...
