Used as a hole-transporting material in organic solar cells and perovskite solar cells due to its excellent charge mobility and stability. It enhances device efficiency by facilitating the movement of positive charges from the active layer to the electrode. Also applied in organic field-effect transistors (OFETs) and light-emitting diodes (OLEDs) as a key component for improving electrical conductivity and device performance. Its structure containing nitrogen and sulfur, along with a planar molecular structure, supports strong π-π stacking, which promotes efficient charge transport in thin-film electronics. Additionally, it serves as a precursor in the synthesis of conductive polymers with special properties for chemical and biological sensors, owing to its sensitivity to environmental changes.
