2,4,7-Trinitrofluorenone is a chemical compound from the group of aromatic nitro compounds .
presentation
1905 described Julius Schmidt and Karl Bauer the synthesis of 2,6,7-trinitrofluorenone by nitration of fluorenone 1 with nitrating acid . Alternative syntheses - the nitration of 2,5-dinitrofluorenone 2 or 2,7-dinitrofluorenone 3 - showed in 1943 that the compound described in 1905 is 2,4,7-trinitrofluorenone 4 .
use
Like picric acid , 2,6,7-trinitrofluorenone also forms stable colored electron donor acceptor complexes with a sharp melting point with numerous polycyclic aromatic hydrocarbons , which are suitable for characterizing and purifying these hydrocarbons.
2,6,7-Trinitrofluorenone is used as a sensitizer in the manufacture of photorefractive polymer composites .
