Description

4,4',4''-(Benzene-1,3,5-Triyltris(Ethyne-2,1-Diyl))Tribenzoic Acid is a high-purity, multifunctional organic building block characterized by its rigid, star-shaped molecular architecture with three carboxylic acid termini. This compound matters for its exceptional utility as a precursor in the synthesis of advanced porous materials and coordination polymers, particularly Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs). It is primarily needed by R&D chemists and material scientists in the fields of advanced materials science, gas storage, heterogeneous catalysis, and optoelectronics.

Application

• MOF/COF Synthesis: A key organic linker for constructing highly porous, crystalline frameworks with large surface areas for gas adsorption (H₂, CO₂, CH₄) and separation.
• Advanced Polymer Chemistry: Serves as a trifunctional monomer for creating hyperbranched polymers and cross-linked networks with tailored thermal and mechanical properties.
• Supramolecular Chemistry: Used in the design and assembly of complex, pre-defined nanostructures and molecular devices via coordination-driven self-assembly.
• Catalyst Support Fabrication: The rigid backbone and functional groups allow for the immobilization of catalytic metal centers, creating efficient heterogeneous catalysts.
• Optoelectronic Materials: Acts as a core component in the development of organic semiconductors, light-emitting materials, and sensors due to its conjugated system.
• Pharmaceutical Intermediates: Potential use as a sophisticated scaffold in medicinal chemistry for the development of novel active pharmaceutical ingredients (APIs).
