Used as a key intermediate in the synthesis of functional organic materials, particularly in the development of optoelectronic compounds. It serves in the preparation of carbazole-based dyes and pigments due to its strong electron-donating properties and thermal stability. Applied in the fabrication of organic semiconductors and light-emitting diodes (OLEDs), where it contributes to tuning emission colors and improving device efficiency. Also utilized in research for photovoltaic materials and as a building block in the design of fluorescent sensors and bioimaging agents.
