Used primarily in organic electronics as a key intermediate in the synthesis of high-performance hole-transport materials. It plays an important role in the development of OLEDs (organic light-emitting diodes) and perovskite solar cells due to its strong electron-donating properties and good thermal stability. Its conjugated structure enhances charge mobility, making it suitable for use in emissive layers and as a building block for dyes and fluorescent probes. Also employed in research for nonlinear optical materials and sensors.
