Description

[1,1':3',1''-Terphenyl]-4,4''-Dicarboxylic Acid, 5'-(4-Carboxy-3,5-Difluorophenyl)-3,3'',5,5''-Tetrafluoro- is a highly fluorinated, multi-carboxylic acid terphenyl derivative, serving as a sophisticated organic building block. Its value lies in its rigid, conjugated aromatic core and multiple reactive sites, enabling the synthesis of advanced materials with tailored electronic and structural properties. This compound is essential for researchers and manufacturers in the fields of organic electronics, metal-organic frameworks (MOFs), and high-performance polymer synthesis.

Application

• Organic Semiconductor Precursor: A key monomer for constructing n-type or ambipolar organic semiconductors used in OFETs (Organic Field-Effect Transistors) and OLEDs (Organic Light-Emitting Diodes).
• Metal-Organic Framework (MOF) Linker: The multiple carboxylate groups and fluorinated aromatic rings allow for the creation of MOFs with unique porosity, stability, and potential for gas storage or separation.
• High-Performance Polymer Monomer: Used in the synthesis of polyimides, polyamides, or other engineering plastics that require exceptional thermal stability, chemical resistance, and low dielectric constants.
• Liquid Crystal Materials: The elongated, rigid terphenyl structure makes it a candidate for core units in fluorinated liquid crystal compounds for display technologies.
• Pharmaceutical Intermediate: Serves as a complex scaffold in medicinal chemistry for the development of novel active pharmaceutical ingredients (APIs), leveraging its fluorine atoms for metabolic stability.
• Advanced Coating Additive: Imparts surface modification, hydrophobicity, and durability to specialty coatings.
