This chemical is primarily used as a key component in the development of organic electronic materials. It serves as an effective hole-transporting material in organic light-emitting diodes (OLEDs) and organic photovoltaic (OPV) devices due to its excellent charge-carrier mobility and stability. Its unique structure enhances the performance and longevity of these devices by improving the efficiency of electron transfer processes. Additionally, it is utilized in the synthesis of advanced polymers and coatings, where its phosphonic acid group enables strong adhesion to various surfaces, making it valuable in creating durable and high-performance materials.
