Used in organic light-emitting diodes (OLEDs) as an efficient fluorescent emitter due to its strong luminescence and thermal stability. Its rigid boron-containing framework enhances electron transport, making it suitable for blue-emitting layers in display technologies. Also explored in bioimaging probes owing to its deep tissue penetration under near-infrared excitation and resistance to photobleaching. Serves as a building block in conjugated polymers for flexible electronics and sensors.
