Description

[1,1':3',1'':3'',1'''-Quaterphenyl]-4,4'''-Dicarboxaldehyde, 5',5''-Bis(4-Formylphenyl)-2',2'',4',4'',6',6''-Hexamethyl- (9Ci) is a high-purity, multi-functional organic building block characterized by its extended conjugated quaterphenyl core and multiple aldehyde functional groups. This compound matters for its role as a critical precursor in the synthesis of advanced organic electronic materials and sophisticated macrocyclic structures. It is primarily needed by R&D chemists and process engineers in the organic electronics, pharmaceutical intermediates, and specialty polymer sectors, where precise molecular architecture is paramount.

Application

• Organic Light-Emitting Diode (OLED) Materials: Serves as a key intermediate for synthesizing electron-transport materials, host materials, and emitting layer components.
• Pharmaceutical Intermediates: Used in the construction of complex, polycyclic active pharmaceutical ingredients (APIs) and drug candidates.
• Liquid Crystal (LC) and Display Technology: Acts as a rigid core unit for developing novel liquid crystal molecules with tailored optical properties.
• Metal-Organic Frameworks (MOFs): Functions as a multi-dentate organic linker for constructing porous coordination polymers with specific pore geometries.
• Specialty Polymers and Dendrimers: Employed as a branching or cross-linking agent to create polymers with high thermal stability and unique optoelectronic characteristics.
• Fluorescent Dyes and Sensors: Utilized as a scaffold for developing fluorescent probes and chemosensors due to its conjugated backbone.
• Academic and Industrial Research: A valuable tool for exploring novel conjugated systems and supramolecular chemistry.
