Used in organic semiconductor materials due to its extended aromatic structure and sulfur-containing functional group, enhancing charge transport properties. Commonly applied in the development of organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). Its rigid fused-ring system improves thermal stability and film-forming ability, making it suitable for thin-film electronic devices. Also investigated as a building block in conjugated polymers for flexible electronics and optoelectronic applications.
