Used in organic synthesis as a multifunctional building block for constructing conjugated organic frameworks. Its aldehyde groups enable Schiff base formation, making it suitable for synthesizing covalent organic frameworks (COFs) and metal-organic frameworks (MOFs). Commonly employed in the development of fluorescent sensors due to its extended π-conjugation, which enhances photophysical properties. Also applied in materials science for fabricating electroluminescent devices and organic semiconductors. The compound’s rigid terphenyl backbone supports structural stability in thin films and nanostructures.
