Rubrene is widely used in organic electronics due to its excellent charge transport properties. It is a key material in the fabrication of organic light-emitting diodes (OLEDs), where it enhances efficiency and brightness. Additionally, rubrene is employed in organic field-effect transistors (OFETs) to improve device performance. Its high photoluminescence quantum yield makes it suitable for use in light-emitting devices and sensors. Rubrene is also utilized in research to study exciton dynamics and energy transfer processes in organic semiconductors. Its stability and optical properties further make it a candidate for applications in photovoltaic devices and optoelectronic systems.
