Description

4-Iodo-1,1':3',1''-Terphenyl CAS NO 34177-25-8 is a high-purity, functionalized terphenyl derivative designed for advanced materials research and organic synthesis. This compound serves as a critical building block and intermediate for creating complex molecular architectures due to its rigid, planar core and reactive iodine substituent. It is essential for researchers and manufacturers in the fields of organic electronics, pharmaceutical development, and liquid crystal materials who require precise molecular control.

Application

• Organic Light-Emitting Diode (OLED) Materials: As a key intermediate for synthesizing host or dopant materials in emissive layers.
• Pharmaceutical Intermediates: Used in the synthesis of complex drug candidates, particularly in cross-coupling reactions like Suzuki or Sonogashira couplings.
• Liquid Crystal (LC) Compounds: Serves as a rigid core unit for developing new liquid crystalline materials with specific optical and electronic properties.
• Organic Semiconductors: A precursor for constructing p-type or n-type semiconducting molecules used in transistors and sensors.
• Metal-Organic Framework (MOF) Linkers: The iodine group can be further functionalized to create novel ligands for porous coordination polymers.
• Polymer Chemistry: Acts as a monomer or chain-extender for creating high-performance, conjugated polymers.
• Chemical Research & Development: A versatile reagent for exploring new organic transformations and catalysis.
