Fluorescence Spectroscopy of AdamBODIPY Single Crystals

Interest in the fluorescence of organic solids is increasing with the development of nanosensors and research into new molecules with aggregation-induced fluorescence properties. We have gone beyond the qualitative observation of fluorescence by…

Etude de nanosystèmes fluorescents, photochromes et plasmoniques : du comportement macroscopique à l’objet individuel

Ce travail de thèse propose d’étudier les propriétés photophysiques de systèmes moléculaires à la fois photochromes et fluorescents. Sous l’effet de la lumière, ces molécules peuvent subir une désexcitation radiative, non radiative ou une photo…

Revealing the Origins of Mechanically Induced Fluorescence Changes in Organic Molecular Crystals

Mechanofluorochromic molecular materials display a change in fluorescence colour through mechanical stress. Complex structure-property relationships in both the crystalline and amorphous phases of these materials govern both the presence and…

Spectroscopic Investigation of Diarylethene Photochromes Linked to Silica Nanoparticles

The spectroscopic properties of silica nanoparticles decorated with fluorescent photochromic molecules at their surface were studied by combining UV−visible spectroscopy with fluorescence correlation spectros-copy on diluted samples of particles…

β-Diketone derivatives: influence of the chelating group on the photophysical and mechanofluorochromic properties

A diphenyl-boron β-diketonate complex was synthesized. Its photophysical properties were studied in solution and in the solid-state, and compared to those of its parent diketone and the corresponding difluoro-boron complex. TD-DFT calculations show…

Topology-Selective Fluorescent "Light-Up" Probes for G-Quadruplex DNA Based on Photoinduced Electron Transfer

Six novel probes were prepared by covalent attachment of a G4-DNA ligand (PDC) to various coumarin or pyrene fluorophores. In the absence of DNA, the fluorescence of all probes is quenched due to intramolecular photoinduced electron transfer (PET)…
