Used as a key building block in the synthesis of conjugated polymers and organic electronic materials. Its dual amine functionality allows for incorporation into polyimides, polyamides, and polyurethanes, enhancing thermal stability and mechanical strength. Frequently employed in the development of high-performance dyes and pigments due to its extended π-conjugation, which contributes to strong light absorption and color intensity. Also utilized in the preparation of nonlinear optical materials and sensors, where the electron-rich structure enables efficient charge transfer. Its rigid, linear structure supports use in molecular wires and nanoscale electronic devices.
