Description

10,10'- Bis (4-Carboxyphenyl) - 9,9'- Diphenyl is a high-purity, functionalized biphenyl derivative designed for advanced material synthesis. This compound is valued for its rigid, aromatic core and terminal carboxylic acid groups, which serve as versatile handles for polymerization and conjugation. It is primarily sought by researchers and manufacturers in the pharmaceutical, OLED, and specialty polymer industries for developing novel organic electronic materials, high-performance resins, and complex molecular architectures.

Application

• Organic Light-Emitting Diode (OLED) Materials: Serves as a key monomer or intermediate in the synthesis of electron-transporting or host materials for display and lighting technologies.
• Pharmaceutical Intermediates: Used in the research and development of active pharmaceutical ingredients (APIs), particularly for constructing complex, conjugated molecular scaffolds.
• High-Performance Polymers: Acts as a dicarboxylic acid monomer for producing polyamides, polyimides, and polyesters with enhanced thermal stability and mechanical properties.
• Metal-Organic Frameworks (MOFs): Functions as an organic linker due to its carboxylate groups, enabling the construction of porous materials for gas storage, separation, or catalysis.
• Liquid Crystal Materials: Utilized as a core building block for creating novel mesogens with specific optical and electronic characteristics.
• Crosslinking Agent: Employed in epoxy resin systems and other thermosetting polymers to increase crosslink density and improve material performance.
