Used as a high-performance organic semiconductor material in thin-film transistors (TFTs), particularly in organic electronics such as flexible displays and printed circuits. Its fused-ring structure with brominated thiophene side groups enhances charge carrier mobility and film stability. Commonly applied in solution-processed devices due to good solubility from the n-octyl chain, enabling low-cost fabrication techniques like spin coating or inkjet printing. Also investigated for use in organic photovoltaics (OPVs) and sensors due to its tunable electronic properties and strong intermolecular stacking.
