Burning TADF solids reveals their excitons’ mobility

Nowadays, Thermally Activated Delayed Fluorescence (TADF) compounds have proven to be attractive for highly efficient optoelectronic devices as they can exploit both singlet and triplet excited states generated by charge recombinations that occur in…

Coating gold nanorods with silica prevents the generation of reactive oxygen species under laser light irradiation for safe biomedical applications

Gold nanoparticles can produce reactive oxygen species (ROS) under the action of ultrashort pulsed light. While beneficial for photodynamic therapy, this phenomenon is prohibitive for other biomedical applications such as imaging, photo-thermal drug…

FRET-mediated quenching of BODIPY fluorescent nanoparticles by methylene blue and its application to bacterial imaging

High resolution and good signal to noise ratio is a requirement in cell imaging. However, after labelling with fluorescent entities, and besides several washing steps, there is often an unwanted fluorescent background that reduces the images…

Is it possible to ”simply” predict the photoejection of a cation? Example of azacrown-substituted [(bpy)Re(CO) 3 L] + complexes

In the context of designing efficient photocontrolled ion-release systems, we propose a ”simple” computational strategy able to predict the cation photoejection. Our strategy is based on TD-DFT calculations and the analysis of the charge transfer …

Synthesis and properties of photoswitchable diphosphines and gold(I) complexes derived from azobenzenes

Diphosphines displaying azobenzene scaffolds and the corresponding bis-gold chloride complexes have been prepared and fully characterized by photophysical, spectroscopic and X-ray diffraction studies. DFT calculations provide complementary…

Triazonine-based bistable photoswitches: synthesis, characterization and photochromic properties

We disclose here dibenzotriazonines as a new class of nine-membered cyclic azobenzenes displaying a nitrogen function in the saturated ring chain. The specific features of these compounds are (i) a preferred E-configuration, (ii) high bi-directional…

Synthesis and chelation study of a fluoroionophore and a glycopeptide based on an aza crown iminosugar structure

Capitalizing on a recently reported iminosugar-based aza-crown (ISAC) accessed by a double Staudinger azaWittig coupling reaction, we have expanded the structural diversity of this new family of sweet cyclam analogs. Replacement of the two secondary…
