Used as a key building block in the synthesis of conjugated porous organic frameworks and covalent organic frameworks (COFs), particularly for applications in gas storage, catalysis, and optoelectronics. Its rigid, star-shaped structure with multiple nitrile groups enables strong π-conjugation and facilitates the formation of extended networks with high surface area. Commonly employed in materials for hydrogen or carbon dioxide capture, and in organic electronics due to its electron-withdrawing nitrile functionalities and structural stability. Also explored in photovoltaic devices and as a precursor for nitrogen-doped carbon materials after pyrolysis.
