Used in the synthesis of conjugated polymers and organic electronic materials due to its ability to act as a building block in Sonogashira coupling reactions. Commonly employed in the development of luminescent materials and sensors, especially for detecting metal ions or volatile organic compounds. Its pyridine ring provides coordination sites for metal ions, making it useful in catalysis and the preparation of metal-organic frameworks (MOFs). Also applied in surface functionalization of carbon nanomaterials and graphene for enhancing dispersion and electronic properties.
