Used extensively as a fluorescent dye in biological imaging and microscopy due to its strong absorption and emission properties in the visible spectrum. It is particularly valuable in staining cellular components, enabling researchers to visualize and study cell structures and processes. Additionally, it serves as a sensitizer in photographic films, enhancing light absorption and improving image quality. Its application in optoelectronic devices, such as organic light-emitting diodes (OLEDs), is also notable due to its efficient light-emitting characteristics.
