25 Centuries of lead white manufacturing processes identified by 13C and 14C carbon isotopes

Synthetic lead carbonates, cerussite and hydrocerussite, have been used for artistic and cosmetic purposes since Antiquity. Commonly known as lead white, the recipes for the manufacture of this pigment are recounted in many treatises on painting…

Nondestructive All-Optical Readout through Photoswitching of Intramolecular Excimer Emission

We report the first intramolecular excimer photoswitching induced by molecular motion within a dithienylethene (DTE) molecule without destructive readout. The photochromic compound DTE bears two pyrene chromophores, judiciously positioned to face…

Photoisomerization of a 4-dicyanomethylene-2-methyl-6-( p -dimethylaminostyryl)-4 H -pyran analog dye: a combined photophysical and theoretical investigation

A combination of experimental and theoretical investigations of a photoisomerizable analog of 4-dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) dye molecule is presented. We provide evidence that the 4 main isomers and conformers…
