Used in organic electronics and optoelectronic devices due to its strong fluorescence and ability to form stable thin films. Commonly employed as a building block in the synthesis of conjugated polymers and small molecules for OLEDs (organic light-emitting diodes) and FETs (field-effect transistors). Its pyrene moiety enables good charge transport and π-π stacking, enhancing device performance. Also utilized in fluorescent sensors and bioimaging probes because of its high quantum yield and photostability. Serves as a fluorescent label or tag in chemical and biological research for tracking molecular interactions.
