Description

[1,1':3',1''-Terphenyl]-4,4'',5'-Tricarboxylic Acid, 2'-Methyl- CAS NO 2305899-77-6 is a high-purity, multi-functional organic building block characterized by its rigid terphenyl backbone and strategically positioned carboxylic acid groups. This compound matters for its role as a key precursor in the synthesis of advanced materials, where its molecular structure enables precise control over material properties. It is primarily needed by researchers and manufacturers in the fields of organic electronics, metal-organic frameworks (MOFs), and specialty polymer chemistry.

Application

• Organic Semiconductor Precursor: Serves as a core building block for the synthesis of novel electron-transport materials (ETMs) and hole-transport materials (HTMs) used in OLEDs and OFETs.
• Ligand for Metal-Organic Frameworks (MOFs): The tricarboxylic acid functionality allows it to act as a multi-dentate organic linker, facilitating the construction of porous MOFs for gas storage, separation, and catalysis.
• Polymer Modification: Used to introduce rigid, aromatic segments and reactive acid sites into polymer chains, enhancing thermal stability and enabling further chemical functionalization.
• Pharmaceutical Intermediate: Employed in the research and development of complex active pharmaceutical ingredients (APIs) that require a sterically defined, polyaromatic core.
• Liquid Crystal Chemistry: Functions as a central unit in the design of discotic or calamitic liquid crystals for display and optoelectronic applications.
• Crosslinking Agent: The multiple acid groups can be utilized to crosslink polymers or resins, improving mechanical strength and chemical resistance in advanced coatings and composites.
