Description

1,1,2,2-Tetrakis(4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl)Ethene is a high-purity, multi-functional organic building block featuring four pinacol boronate ester groups, making it a critical precursor for advanced materials synthesis. Its value lies in its exceptional utility as a tetravalent cross-coupling reagent for constructing complex, rigid, and highly conjugated molecular architectures. This compound is essential for researchers and manufacturers in organic electronics, polymer science, and pharmaceutical development who require precise, multi-directional molecular assembly.

Application

• Organic Light-Emitting Diodes (OLEDs): Serves as a key monomer for synthesizing high-efficiency, star-shaped or cross-linked host and emitter materials.
• Porous Organic Polymers (POPs) & Covalent Organic Frameworks (COFs): Acts as a tetrahedral node for constructing highly porous, crystalline frameworks for gas storage, separation, and catalysis.
• Conjugated Microporous Polymers (CMPs): Used to create materials with tunable optoelectronic properties for sensing and energy storage applications.
• Pharmaceutical Intermediates: Enables the synthesis of complex, multi-armed drug candidates and bioactive molecules via Suzuki-Miyaura cross-coupling reactions.
• Dendrimer & Hyperbranched Polymer Synthesis: Functions as a core unit for building precise, three-dimensional macromolecular structures.
• Cross-linked Polymer Networks: Utilized to create robust, insoluble polymer matrices for coatings, adhesives, and advanced composites.
• Liquid Crystal Materials: A precursor for developing novel, multi-armed mesogens with specific self-assembly properties.
• Chemical Sensors: Building block for fluorescent or colorimetric sensor materials that detect specific ions or small molecules.

Quality Control

Every batch of 1,1,2,2-Tetrakis(4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl)Ethene is synthesized and purified under controlled conditions to ensure consistent high quality and performance. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with stringent industry standards for research and production. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment, preferably under an inert atmosphere such as argon or nitrogen for long-term storage. Keep away from incompatible materials.
