Used as a hole-transporting material in organic light-emitting diodes (OLEDs) due to its excellent thermal stability and favorable electronic properties. It helps improve device efficiency by facilitating the movement of positive charges within the emissive layer. Also investigated in perovskite solar cells for its ability to enhance charge extraction and device performance. Its rigid, planar structure supports strong intermolecular interactions, contributing to better film formation and long-term stability in optoelectronic devices.
