Étude des propriétés acido-basiques d'un composé photochrome de la famille des spiropyranes

Le composé photochrome appelé 6-NO2-BIPS peut subir une transformation réversible entre une forme normale (N) et une forme mérocyanine (MC). L’irradiation UV permet de transformer la forme N en MC alors que le retour de la forme MC à la forme N est…

Anion‐π Interaction for Molecular Recognition of Anions: Focus on Cooperativity with Hydrogen Bonding

Anion recognition represents an active area of research in supramolecular chemistry. The last two decades have been marked by spectacular advances in the design of new anion receptors. Moreover, the development of approaches combining experimental…

Lead(II) Formate in Rembrandt's Night Watch : Detection and Distribution from the Macro‐ to the Micro‐scale

The Night Watch, painted in 1642 and on view in the Rijksmuseum in Amsterdam, is considered Rembrandt's most famous work. X-ray powder diffraction (XRPD) mapping at multiple length scales revealed the unusual presence of lead(II) formate, Pb(HCOO) 2…

ESIPT-Active cinnamoyl pyrones are bright solid-state emitters: Revisited theoretical approach and experimental study

Excited-state intramolecular proton transfer (ESIPT) is a photophysical process that may lead to superior emission properties. For a long time, cinnamoyl pyrone (CP) derivatives have been classified as non-ESIPT molecules. With the exception of…

Virtual technical analysis of archaeological textiles by synchrotron microtomography

Archaeological textile remains from Antiquity are rare due to their perishable nature. In certain cases, the conservation of the morphology and / or of chemical signatures can be exquisite. Detailed archaeological information on the social and…

Ultrafast time-resolved spectroscopy elucidating photo-driven electron and energy transfer processes in a broadband light-absorbing BODIPY-C60-distyryl BODIPY triad

Photoinduced electron and energy transfer pathways are elucidated in a panchromatic light-absorbing, covalently linked triad (BODIPY-C60-distyryl BODIPY, noted as BDP-C60-DSBDP) along with the two reference dyads: BODIPY-C60 (BDP-C60) and distyryl…

TRANSFERRING RESEARCH TO TEACHING - THE CASE OF PHOTOCHROMISM

Photochromism is the reversible transformation of a chemical specie between two forms by the absorption of light (photoisomerization), where the two forms have different absorption spectra. It can be considered as a fast growing domain of research…

Universal Buffer : a powerful tool to investigate the impact of pH on photophysical and (photo)chemical properties from 1.9 to 12.

pH can impact a wide range of (photo)chemical (kinetics, thermodynamics or quantum yield…) or photophysicals properties (absorption, emission…). We proposed to present an easy, fast and reproducible new method to tune with a very high precision pH…
