Used in organic semiconductor fabrication, particularly in the development of high-performance organic thin-film transistors (OTFTs). It serves as a key precursor in the synthesis of dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT), which exhibits excellent charge carrier mobility and environmental stability. Due to these properties, it is widely applied in flexible electronics, display drivers, radio-frequency identification (RFID) tags, and sensor technologies. Its ability to form well-ordered thin films through solution or vapor-phase deposition makes it suitable for large-area and low-cost electronic devices.
