Used as a key building block in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), this compound enables the creation of porous materials with high surface areas. Its multiple amino and carboxylic acid functional groups allow for strong coordination with metal ions and participation in condensation reactions, making it valuable for designing frameworks used in gas storage, catalysis, and chemical sensing. Due to its rigid aromatic structure and directional binding sites, it contributes to the structural stability and porosity of the resulting networks. It is also explored in the development of advanced materials for proton conduction and environmental remediation, such as adsorption of heavy metals or CO₂ capture.
