Phoyunbene C is widely used in the development of organic semiconductor materials due to its extended π-conjugated structure. It serves as a key building block in the synthesis of high-performance electronic materials, particularly in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid aromatic framework enhances charge carrier mobility and thermal stability, making it suitable for thin-film devices. Additionally, Phoyunbene C derivatives are explored in light-emitting diodes (OLEDs) for their tunable emission properties. The compound’s compatibility with solution-processing techniques supports its use in low-cost, large-area printable electronics.
