Description

Tetrakis(4-Ethynylphenyl)Ethene is a high-purity, functionalized organic building block featuring a central ethene core with four peripheral ethynylphenyl groups. This compound matters for its role as a versatile precursor in advanced materials science, enabling the synthesis of complex molecular architectures through cross-coupling and polymerization reactions. It is primarily needed by researchers and manufacturers in the fields of organic electronics, polymer chemistry, and materials engineering for developing novel conjugated polymers, porous organic frameworks, and luminescent materials.

Application

• Advanced Polymer Synthesis: Serves as a key monomer for constructing hyperbranched or cross-linked conjugated polymers with tailored electronic properties.
• Metal-Organic Frameworks (MOFs) & Covalent Organic Frameworks (COFs): Acts as a multi-functional organic linker for creating porous, crystalline materials with high surface areas for gas storage or catalysis.
• Organic Light-Emitting Diodes (OLEDs) & Photovoltaics: Used as a core building block for developing novel emitters or electron-transport materials in optoelectronic devices.
• Chemical Sensing Platforms: Incorporated into polymeric or framework structures to create sensitive layers for detecting specific analytes due to its π-conjugated system.
• Surface Functionalization: Employed to modify material surfaces via "click" chemistry (e.g., CuAAC), introducing ethynyl groups for further chemical grafting.
• Academic & Industrial R&D: A critical reagent for exploratory research in supramolecular chemistry and the development of new functional materials.
