Used as a key building block in the synthesis of covalent organic frameworks (COFs), particularly for creating porous, stable, and highly ordered structures with potential applications in gas storage, catalysis, and optoelectronics. Its four peripheral amine groups enable strong imine bond formation, facilitating the construction of robust 2D and 3D networks. Also employed in the development of functional polymers and sensors due to its electron-rich aromatic structure and ability to participate in charge-transfer interactions. Shows promise in energy storage materials and as a precursor for nitrogen-doped carbon materials after pyrolysis.
