Bright Lanthanide III Triboluminescence despite Low Photoluminescence, and Dual Triboluminescence and Mechano‐Responsive Photoluminescence

reactions in organic solvents. Mechanochromic luminescence (MCL) describes the deformation of molecular conformations alongside changed optical properties in response to mechanical stimuli. Crystalto-crystal/amorphous phase transitions produce…

s-Tetrazine derivative exhibiting unprecedented polymorphism-dependent emission properties

The first example of a tetrazine derivative exhibiting emission color-tunable crystals upon external stimuli such as heat and an organic solvent is described. Bis(4-methylphenoxy)tetrazine (1) forms several crystalline phases by heating and cooling…

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…

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…
