Chrysene is primarily used in research and industrial applications related to organic semiconductors and optoelectronic materials. Due to its polycyclic aromatic structure, it exhibits favorable electronic properties, making it a useful building block in the development of organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). It is also employed as a fluorescent probe in environmental and biochemical studies, helping detect and analyze aromatic pollutants. In addition, chrysene derivatives are investigated for their potential in photodynamic therapy and as sensors for explosive compounds due to their luminescent behavior. Its stability under thermal and photochemical conditions further supports its role in material science applications.
