Description

4',5'-Bis(3,5-Dicarboxyphenyl)-[1,1':2',1"-Terphenyl]-3,3'',5,5"-Tetracarboxylic Acid is a high-purity, multi-functional aromatic carboxylic acid building block of significant interest in advanced materials science. Its complex, rigid structure and high density of carboxyl groups make it a critical precursor for synthesizing sophisticated metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). This compound is essential for researchers and manufacturers developing next-generation materials for gas storage, separation, catalysis, and sensing applications.

Application

• MOF/COF Synthesis: Primary building block (ligand) for constructing highly porous and crystalline framework materials with tailored pore sizes and chemical functionality.
• Gas Storage & Separation: Used in frameworks designed for the selective capture and storage of gases such as hydrogen, methane, and carbon dioxide.
• Heterogeneous Catalysis: Serves as a structural component in frameworks that act as catalysts for organic transformations, offering high surface area and active sites.
• Chemical Sensing: Enables the creation of luminescent or colorimetric sensors for detecting specific ions, molecules, or environmental changes.
• Proton Conduction: Used in the development of framework materials for proton-exchange membranes in fuel cell technology.
• Advanced Polymer Research: Acts as a monomer or cross-linker for synthesizing high-performance polyimides and other specialty polymers with exceptional thermal and chemical stability.
• Pharmaceutical Intermediates: Potential use in the synthesis of complex, multi-cyclic drug candidates due to its intricate aromatic core.
