pyrene profile

Pyrene is a polycyclic aromatic hydrocarbon consisting of four fused benzene rings. It is a white solid that is poorly soluble in water but soluble in organic solvents. Pyrene is a highly fluorescent molecule that is used in a variety of applications, including organic light-emitting diodes (OLEDs), chemical sensors, and biological imaging. The molecule is also found in the environment, where it is produced by the incomplete combustion of organic materials. Pyrene's toxicity is a concern due to its potential for DNA damage and other adverse health effects. It is a common contaminant of water and soil. Its synthesis involves a variety of methods, including the pyrolysis of coal and the synthesis of specific precursors such as acenaphthene or phenanthrene. It is a model system for understanding the electronic structure and reactivity of polycyclic aromatic hydrocarbons.'
