Widely used in metal–organic frameworks (MOFs), this chemical acts as a rigid, tridentate linker that connects metal ions or clusters to form porous, highly ordered structures. These frameworks are applied in gas storage, particularly for hydrogen and carbon dioxide, due to their high surface area and tunable pore size. It is also employed in catalysis, where the nitrogen-rich environment enhances the dispersion and stability of catalytic metal sites. Additionally, it plays a role in sensing applications, showing selective fluorescence response to specific metal ions or volatile organic compounds. Its structural rigidity and ability to form stable coordination networks make it valuable in designing functional materials for environmental and energy-related technologies.
