Microchemical Imaging of Oil Paint Composition and Degradation: State-of-the-Art and Future Prospects

Oil paint is a dynamic system that undergoes chemical alteration on several time and length scales. At the short term, curing reactions are necessary for oil to dry properly. At longer time scales, a wide variety of other chemical processes can…

On the road for more efficient biocompatible two-photon excitable fluorophores

Red to NIR absorption and emission wavelengths are key requirements for intravital bioimaging. One of the way to reach such excitation wavelengths is to use two-photon excitation. Unfortunately, there is still a lack of two-photon excitable…

Trialkoxyheptazine-Based Glyconanoparticles for Fluorescence in Aqueous Solutions and on Surfaces via Controlled Binding in Space

The fluorescent organic 2,5,8-tris((adamantan-1-yl) methoxy)-heptazine (HTZ-Ad) was solubilized in water by inclusion of adamantane groups into free β-cyclodextrins or cyclodextrin shell of glyconanoparticles. These glyconanoparticles with average…

Visible‐Light‐Initiated Palladium‐Catalyzed Cross‐coupling by PPh3 Uncaging from an Azobenzene Ruthenium–Arene Complex

Triphenylphosphine photo-release from a sulfonamide azobenzene ruthenium-arene complex was exploited to activate Pd(II)Cl2 into Pd(0) catalyst, for the photo-initiation of Sonogashira cross-couplings. The transformation was initiated on demand –…

Synthesis and Spectroscopic Characterization of Novel Thiourea-Bearing Photoactivatable NADPH Mimics Targeting NO Synthases

Abstract A new set of photoactivatable NADPH mimics bearing a thiourea linkage between a diarylbutadiene and an adenosine moiety functionalized by O-carboxymethyl groups has been designed and synthesized in a convergent strategy. These compounds…

4,4’-Dimethylazobenzene as a Chemical Actinometer

Chemical actinometers are a useful tool in photochemistry, which allows to measure the photon flux of a light source to carry out quantitative analysis on photoreactions. The most commonly employed actinometers so far show minor drawbacks, such as…

The “Historical Materials BAG”: A New Facilitated Access to Synchrotron X-ray Diffraction Analyses for Cultural Heritage Materials at the European Synchrotron Radiation Facility

The European Synchrotron Radiation Facility (ESRF) has recently commissioned the new Extremely Brilliant Source (EBS). The gain in brightness as well as the continuous development of beamline instruments boosts the beamline performances, in…
