Description

4,4',4'',4'''-([1,1'-Biphenyl]-3,3',5,5'-Tetrayltetrakis(Ethyne-2,1-Diyl))Tetrabenzoic Acid is a sophisticated, multi-functional organic building block featuring a rigid, conjugated biphenyl core extended with four benzoic acid groups via ethynylene linkers. This compound matters for its unique structural properties, offering a combination of precise geometry, thermal stability, and multiple reactive sites for constructing advanced materials. It is primarily needed by researchers and manufacturers in the fields of organic electronics, metal-organic frameworks (MOFs), and specialty polymers.

Application

• Metal-Organic Framework (MOF) Synthesis: Serves as a high-connectivity, rigid organic linker for constructing porous, crystalline materials for gas storage, separation, and catalysis.
• Conjugated Polymer Precursor: Used in the synthesis of advanced polymers for organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and field-effect transistors (OFETs).
• Supramolecular Chemistry: Acts as a key component for designing complex molecular architectures and self-assembled systems due to its directional bonding capability.
• Surface Functionalization: The carboxylic acid groups enable covalent attachment to metal oxides and other surfaces for sensor development and nano-fabrication.
• Cross-linking Agent: Utilized in the production of high-performance, thermally stable resins and network polymers.
• Academic & Industrial R&D: A valuable intermediate for exploring new materials in photonics, electronics, and nanotechnology.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request. We adhere to a cGMP-compliant quality management system suitable for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider using a desiccator or inert atmosphere.
