Three ureido-pyrimidone derivatives (N-LH) were used to generate in combination with four dinuclear arene ruthenium clips, (p-cymene) 2Ru2(OO boolean AND OO)Cl2 (OO boolean AND OO = oxalato, 2,5-dioxido-1,4-benzoquinonato, 2,5-dichloro-1,4-benzoquinonato, 5,8-dioxido-1,4-naphtoquinonato), twelve cationic arene ruthenium metalla-cycles of the...

The aim of the present thesis was to explore new approaches in the design and synthesis of new arene ruthenium species. This class of organometallic compounds has been the subject of much attention in the recent years due to their interesting properties in various fields, such as medicinal chemistry or supramolecular chemistry. In order to achieve this goal, this work was divided into two...

The possibility to change the molecular assembled structures of organic and organometallic materials through mechanical stimulation is emerging as a general and powerful concept for the design of functional materials. In particular, the photophysical properties such as photoluminescence color, quantum yield, and emission lifetime of organic and organometallic fluorophores can significantly depend...

Multiresponsive materials that display predefined photoluminescence color changes upon exposure to different stimuli are attractive candidates for advanced sensing schemes. Herein, we report a cyano-substituted oligo(p-phenylene vinylene) (cyano-OPV) derivative that forms five different solvent-free solid-state molecular assemblies, luminescence properties of which change upon thermal and...

Sequential insertion of different dyes into the 1D channels of zeolite L (ZL) leads to supramolecular sandwich structures and allows the formation of sophisticated antenna composites for light harvesting, transport, and trapping. The synthesis and properties of dye molecules, host materials, composites, and composites embedded in polymer matrices, including two- and three-color antenna systems,...

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...

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...

Ce travail traite de l’incorporation de métaux dans des assemblages dendritiques pour obtenir des propriétés liquides-cristallines ou biologiques. L’arrangement spatial des nanoparticules d’or est actuellement un défi pour obtenir des métamatériaux. Les associer à des dendrimères liquides-cristallins est une possibilité pour les organiser dans des mésophases. Nous...
