Description

4',4'',4''',4''''-(Ethene-1,1,2,2-Tetrayl)Tetrabiphenyl-4-Carboxylic Acid is a high-purity, multi-functional organic compound featuring a rigid, conjugated tetraphenylethylene (TPE) core peripherally functionalized with carboxylic acid groups. This unique molecular architecture makes it a critical advanced intermediate for synthesizing sophisticated materials with precise electronic and optical properties. It is primarily sought by R&D and production teams in the organic electronics, advanced material science, and pharmaceutical research sectors.

Application

• Organic Light-Emitting Diodes (OLEDs): Serves as a key precursor for electron-transport materials (ETMs) or host materials in emissive layers.
• Metal-Organic Frameworks (MOFs): Acts as a versatile organic linker or strut due to its multiple carboxylate coordination sites and rigid backbone.
• Polymer & Dendrimer Synthesis: Used as a core building block for constructing hyperbranched polymers, star-shaped molecules, or covalent organic frameworks (COFs).
• Fluorescent Sensors & Probes: Utilized in the development of aggregation-induced emission (AIE)-active sensors for detecting ions, biomolecules, or environmental analytes.
• Pharmaceutical Intermediates: Employed in the research and synthesis of complex drug candidates, particularly those requiring a rigid, multi-armed scaffold.
• Liquid Crystal & Electro-Optic Materials: Functions as a core component for designing novel liquid crystalline compounds with specific mesophases.
