General description
Picric acid (PA, 2,4,6-trinitrophenol) is a polynitrated aromatic acid. It is strongly acidic in nature. Since it readily dissolves in water, it can easily pollute the environment on exposure. Sensitive detection of PA by tris-imidazolium salt, fluorescent [3+2] self-assembled nanoscopic organic cage and rhodamine based sensors have been reported. It is widely used for the determination of various organic compounds by spectrophotometric and extractive spectrophotometric methods.
