Used as a key intermediate in the synthesis of conductive polymers, particularly in organic electronics such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its fused heterocyclic structure enhances charge carrier mobility and stability when incorporated into polymer backbones. It is especially valuable in donor-acceptor type copolymers for improving thin-film morphology and enabling solution-processable fabrication methods. Also explored in organic light-emitting diodes (OLEDs) due to its ability to support efficient hole transport.
