Description

[1,1':4',1''-Terphenyl]-3,4'',5-Tricarboxylic Acid CAS NO 1637760-07-6 is a high-purity, multi-functional aromatic carboxylic acid derivative, serving as a critical building block in advanced materials science. Its value lies in its rigid, planar terphenyl core and three precisely positioned carboxylic acid groups, which enable precise molecular design and robust framework construction. This compound is essential for researchers and manufacturers in the fields of metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and specialty polymer synthesis.

Application

• Organic Semiconductor Precursor: Acts as a key monomer for constructing conjugated polymers and small molecules used in OLEDs, OFETs, and photovoltaic cells.
• Metal-Organic Framework (MOF) Linker: The three carboxylate groups provide excellent coordination sites for metal ions (e.g., Zr4+, Cu2+), creating porous MOFs for gas storage, separation, and catalysis.
• Covalent Organic Framework (COF) Building Block: Used in condensation reactions to form highly ordered, crystalline porous polymers for sensing and catalytic applications.
• Polymer Modification: Serves as a cross-linking agent or functional monomer to introduce rigidity and thermal stability into polyimides, polyesters, and epoxy resins.
• Pharmaceutical Intermediate: Utilized in the synthesis of complex drug molecules where a rigid, multi-functional aromatic core is required.
• Liquid Crystal Material Synthesis: The terphenyl backbone is ideal for creating mesogenic units in advanced liquid crystal displays (LCDs).
• Analytical Chemistry Standard: Employed as a high-purity reference standard in chromatographic analysis and material characterization.
