Used as a key building block in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), this compound acts as a multitopic linker due to its four carboxylic acid groups. Its rigid, three-dimensional structure helps create porous materials with high surface areas, suitable for gas storage, catalysis, and molecular separation. The extended aromatic system enhances stability and promotes π-π interactions, making it valuable in designing functional porous materials for environmental and energy applications.
