Used as a high-performance red fluorescent dye in organic light-emitting diodes (OLEDs), particularly in deep-red and near-infrared emission devices. Its rigid, planar structure enhances luminescence efficiency and thermal stability, making it suitable for display technologies and optoelectronic sensors. Also investigated for use in photodynamic therapy and as a spectral down-conversion material in bioimaging due to its strong emission in the therapeutic optical window.
