9-(2-Naphthyl)anthracene is primarily used in the field of organic electronics due to its excellent photophysical properties. It is employed as a luminescent material in organic light-emitting diodes (OLEDs), where it contributes to high efficiency and brightness in display and lighting technologies. Additionally, its ability to form stable thin films makes it suitable for use in organic photovoltaic cells, enhancing their light absorption and energy conversion efficiency. In research, it serves as a model compound for studying charge transport and energy transfer processes in conjugated organic molecules. Its fluorescence properties also make it useful in sensor applications, particularly in detecting environmental pollutants or specific chemical species.
