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 …

Cyclometalated Rhodium and Iridium Complexes Containing Masked Catecholates: Synthesis, Structure, Electrochemistry, and Luminescence Properties

Two neutral cyclometalated rhodium and iridium coordination assemblies [(F2ppy)2M(η-Cat)], M = Rh, (2) and M = Ir, (3) (F2ppy: 2,4-difluorophenylpyridine), displaying a masked catecholate (η-Cat = η-O∧O) are described. The catecholate ligand is π…

Physiological synaptic activity and recognition memory require astroglial glutamine

Abstract Presynaptic glutamate replenishment is fundamental to brain function. In high activity regimes, such as epileptic episodes, this process is thought to rely on the glutamate-glutamine cycle between neurons and astrocytes. However the…

How to do photophysics with daily life products

Fluorescence is defined as the emission of light by a substance during its irradiation by electromagnetic radiation. For organic compounds, such phenomena is called molecular fluorescence and the light source for the irradiation is usually UV or…
