This polymer is widely used in the field of organic electronics due to its excellent hole-transporting properties. It is commonly applied as a key material in organic light-emitting diodes (OLEDs) to enhance device efficiency and stability. Additionally, it serves as a functional layer in organic photovoltaic (OPV) cells, where it facilitates efficient charge transport and improves overall performance. Its thermal stability and solubility in organic solvents make it suitable for solution-based processing techniques, such as spin-coating and inkjet printing, which are essential for large-scale manufacturing of flexible electronic devices.
