Luminescence-Sensitive Surfaces Bearing Ratiometric Nanoparticles for Bacteria Growth Detection

pH is one of the most fundamental parameters describing the quality of an aqueous solution. We developed a ratiometric fluorescent platform to monitor pH not only in solution but also on surfaces: our nanoprobe is based on fluorescent nanoparticles …

Polymères mécanofluorochromes comme sondes de contraintes mécaniques

Parmi les matériaux intelligents, ceux qui sont mécanochromes (MC) ou mécanofluorochromes (MFC) répondent à des stimuli mécaniques par une modification de leurs propriétés d’absorption UV-Visible ou d’émission de fluorescence respectivement. La…

Perylene based PET fluorescent molecular probes for pH monitoring

New perylene-based pH probes have been synthesized and utilized for the development of pH optodes. These amine-functionalized perylene-based probes display high molar absorption coefficients in the visible range and protonated forms are…

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…
