3,5-Bis(2,4-dinitrophenyl)-4-nitro-1H-pyrazole acetone monosolvate
Acta Crystallographica Section E, 2012 The title structure, C15H7N7O10·C3H6O, was prepared by pentanitration of 3,5-diphenyl-1H-pyrazole. The proton attached to a pyrazole N atom forms a hydrogen bond with the O atom of the acetone solvent molecule, owing to the NO2 enhanced acidity ...

Expanding the Repertoire of Photoswitchable Unnatural Amino Acids for Enzyme Engineering
Angewandte Chemie International Edition, EarlyView.Enzyme engineering with photoswitchable unnatural amino acids (psUAAs) has a high potential for applications such as biocatalysis. Here, we extend the current repertoire of psUAAs to include more versatile properties paving the way to more advanced photocontrol engineering.
