Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for applications in gas storage and separation due to its rigid aromatic structure and multiple coordination sites. Its zwitterionic nature enhances interactions with metal ions, improving framework stability. Also explored in catalysis and proton-conductive materials for fuel cell membranes owing to its ability to form extended hydrogen-bonding networks. Shows potential in sensing applications because of its fluorescence properties when incorporated into porous frameworks.
