s-Tetrazine Dyes: A Facile Generation of Photoredox Organocatalysts for Routine Oxidations

A series of organic dyes derived from s-tetrazine have been synthesized, and their photophysical and electrochemical properties are systematically investigated. Testing these compounds as photoredox catalysts in a model oxidative C-S bond cleavage…

Electrofluorochromism of Surface-Confined Tetrazines Investigated on the Monolayer Scale

Monolayers of tetrazine terminated alkyl chains have been grafted on ITO through siloxane functions. These monolayers are electroactive and display fluorescence with a maximum close to 560 nm when excited in the visible range. Potential step cycles…

The role of the secondary fluorophore in ternary plastic scintillators aiming at discriminating fast neutrons from gamma-rays

Since Helium-3 shortage announcement, organic scintillators play a major role in neutron detection. Our laboratory decided to focus on plastic scintillators and their ability to discriminate fast neutrons from gamma rays. In this work, we highlight…

Light-induced formation of NO in endothelial cells by photoactivatable NADPH analogues targeting nitric-oxide synthase

Background: Nitric-oxide synthases (NOS) catalyze the formation of NO using NADPH as electron donor. We have recently designed and synthesized a new series of two-photon absorbing and photoactivatable NADPH analogues (NT). These compounds bear one…

Convenient One-Pot Synthesis of 1,2,3,4-Thiatriazoles Towards a Novel Electron Acceptor for Highly-Efficient Thermally-Activated Delayed-Fluorescence Emitters

A novel and unexpected convenient one-pot synthesis of 1,2,3,4-thiatriazoles has been discovered meanwhile investigating on the classical tetrazine "Pinner synthesis". The synthetic route starts from commercially-available nitrile derivatives and…

Bacteria‐Based Production of Thiol‐Clickable, Genetically Encoded Lipid Nanovesicles

Despite growing research efforts on the preparation of (bio)functional liposomes, synthetic capsules cannot reach the densities of protein loading and the control over peptide display that is achieved by natural vesicles. Here we present a microbial…

Fluorenylporphyrins functionalized by electrochromic ruthenium units as redox-triggered fluorescence switches

Two dyads containing tris-and tetrakis-meso-fluorenyl-substituted porphyrin and ethynylruthenium units, 1 and 2, were investigated by emission spectro-electrochemical (SEC) methods for their potential use as fluorescence switches. The ruthenium…
