Description

Benzoic Acid, 4,4',4'',4'''-(1,2,4,5-Benzenetetrayltetra-2,1-Ethynediyl)Tetrakis- is a highly functionalized, multi-branched organic compound featuring a central benzene core extended by ethynylene and benzoic acid groups. This unique molecular architecture makes it a valuable advanced intermediate or building block for synthesizing complex, star-shaped macromolecules and functional materials. It is primarily sought by R&D chemists and material scientists in the fields of organic electronics, polymer science, and supramolecular chemistry.

Application

• Organic Electronic Materials: Serves as a core building block for the synthesis of star-shaped or dendritic molecules used in Organic Light-Emitting Diodes (OLEDs), Organic Photovoltaics (OPVs), and Field-Effect Transistors (OFETs).
• Polymer Science: Acts as a multifunctional monomer or cross-linking agent for creating hyperbranched polymers, dendrimers, and networks with tailored thermal and mechanical properties.
• Metal-Organic Frameworks (MOFs): Utilized as an intricate organic linker to construct MOFs with complex pore structures for gas storage, separation, or catalysis.
• Supramolecular Chemistry: The precise spatial arrangement of carboxylic acid groups enables the design of novel host-guest complexes and self-assembled structures.
• Pharmaceutical & Agrochemical Intermediates: Used in research for developing new active ingredients that require a rigid, multi-armed scaffold.
• Surface Modification & Nanotechnology: Functionalizes surfaces or nanoparticles to create advanced coatings or composite materials.
