Used as a hole-transport material in organic light-emitting diodes (OLEDs) and perovskite solar cells due to its excellent thermal stability and good charge transport properties. Its molecular structure allows for efficient hole injection and mobility, making it suitable for use in high-performance optoelectronic devices. Also employed in organic thin-film transistors (OTFTs) and as a building block in metal-organic frameworks for catalytic applications. Shows potential in photoelectrochemical systems where stable and efficient electron donation is required.
