Used in organic electronics due to its electron-rich structure, particularly in the development of organic semiconductors and conjugated polymers. Its rigid planar framework enhances charge carrier mobility, making it suitable for applications in organic field-effect transistors (OFETs) and as a building block in donor-acceptor type materials for organic photovoltaics (OPVs). Also explored in fluorescent sensors and dyes owing to its extended π-conjugation and tunable emission properties.
