Used as a key building block in the synthesis of advanced organic materials, particularly in the development of conjugated polymers and metal-organic frameworks (MOFs). Its rigid terphenyl backbone and functional amine and carboxylic acid groups enable strong coordination with metal ions and facilitate charge transport, making it valuable in optoelectronic devices such as organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). Also employed in designing porous materials for gas storage and catalysis due to its ability to form stable, structured networks. Its dual functionality allows for post-synthetic modifications, enhancing its utility in sensor development and molecular recognition systems.
