Description

[1,1',4',1",4",1"'-Quaterphenyl]-4,4'''-Dicarboxylic Acid is a high-purity, multi-aromatic ring dicarboxylic acid derivative, serving as a critical advanced organic intermediate. This compound matters for its role as a rigid, linear building block in the synthesis of sophisticated functional materials, where its precise molecular structure is essential. It is primarily needed by manufacturers in the OLED (Organic Light-Emitting Diode) and organic semiconductor industries for creating electron-transport or host materials, as well as by researchers developing metal-organic frameworks (MOFs) and liquid crystals.

Application

• OLED Material Synthesis: A key precursor for constructing electron-transport layers (ETLs) and host materials in high-performance display and lighting technologies.
• Organic Semiconductor Development: Used as a rigid-rod conjugated linker in the creation of novel organic electronic components.
• Metal-Organic Frameworks (MOFs): Acts as an extended organic linker to form porous, crystalline materials for gas storage, separation, and catalysis.
• Liquid Crystal Chemistry: Serves as a core unit in the design of advanced liquid crystalline materials for displays and optical devices.
• Polymer & Advanced Material Research: Incorporated into high-performance polymers and specialty coatings to enhance thermal stability and mechanical properties.
• Pharmaceutical Intermediate: Potential use in the synthesis of complex drug molecules requiring a rigid, multi-phenyl backbone.

Quality Control

Our [1,1',4',1",4",1"'-Quaterphenyl]-4,4'''-Dicarboxylic Acid is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, critical for sensitive electronic and photonic applications. Each lot undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
