Used as an intermediate in the synthesis of conjugated polymers and organic semiconductors for electronic devices such as OLEDs and organic field-effect transistors (OFETs). Serves as a building block in the preparation of dyes and pigments due to its aromatic and heterocyclic structure. Employed in the development of conductive materials and sensors, where the thiophene-aniline combination enhances charge transport properties. Also investigated for use in photovoltaic cells as part of donor-acceptor type copolymers. Its amine functionality allows for easy functionalization and incorporation into larger molecular architectures.
