PTCBI is widely used in the field of organic electronics, particularly in the development of organic photovoltaics (OPVs) and organic light-emitting diodes (OLEDs). Its unique electronic properties make it an effective electron-transport material, enhancing the efficiency and performance of these devices. In OPVs, PTCBI is often employed as an acceptor material in the active layer, facilitating the separation of charge carriers and improving power conversion efficiency. For OLEDs, it serves as an electron injection layer, ensuring better electron mobility and overall device stability. Additionally, PTCBI is utilized in organic field-effect transistors (OFETs) due to its ability to maintain high charge carrier mobility, making it a valuable component in advanced electronic applications.
