Synthèse et caractérisation photophysique de polymères fluorescents à base de polysiloxane pour la détection de composés nitroaromatiques.

Cette thèse présente le travail réalisé sur la mise au point de nouveaux polymères fluorescents à chaînes latérales destinés à détecter des traces de 2,4-dinitrotoluène. Pour atteindre cet objectif nous avons recherché un matériau alliant un…

Multicolor Emission of Small Molecule-Based Amorphous Thin Films and Nanoparticles with a Single Excitation Wavelength

Fluorescent organic nanoparticles (FON) made of small molecules recently arouse considerable interest in biomedical imaging and opto-electronics as potential microlasers or emitting displays.2 Their collective emission largely enhanced with respect…

Ruthenium(II) Complexes for Two-Photon Absorption-Based Optical Power Limiting

Long-lived excitation: Novel bifluorene-substituted 1,10-phenanthroline-based RuII coordination complexes are presented (see picture). They fulfil several requirements for optimized optical power limiting in the visible-NIR, as they are stable,…

Scanning-less wide-field single-photon counting device for fluorescence intensity, lifetime and time-resolved anisotropy imaging microscopy

A scanning-less single-photon counting system for FLIM and fluorescence anisotropy wide-field imaging is described and characterized in this paper. The two polarizations of the fluorescence are divided by a Glan prism and acquired at the same time…

Organic crystals for second harmonic generation switching based on anil photochromes

In photochromic materials, we demonstrated that non-linear optical (NLO) properties such as second harmonic generation (SHG) can be switched reversibly by alternate UV and visible irradiations. We report here on the design of materials fulfilling…

Corrosion resistance of sol-gel coatings doped with an organic corrosion inhibitor: Chloranil

Hybrid sol–gel films have been prepared with diethoxydimethylsilane (DEODMS), methyltriethoxysilane (MTEOS) as a source of hydrolysable silane and tetra-propoxyzirconium (TPOZ) as a source of hydrolysable zirconium. In order to improve corrosion…

Generation of new fluorophore by Click chemistry: synthesis and properties of beta-cyclodextrin substituted by 2-pyridyl triazole

2-Pyridyl triazole substituted P-cyclodextrins, formed by a HUisgen [2+3] cycloaddition reaction between per-(6-azido)-beta-cyclodextrins and 2-ethynylpyridine, exhibited interesting solvent-polarity dependent fluorescence properties and acted as…
