Description

2,2'-(4,4'-Didodecyl-[2,2'-Bithiophene]-5,5'-Diyl)Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane) is a high-purity, functionalized bithiophene monomer bearing pinacol boronate ester groups. This compound is a critical key intermediate in the synthesis of advanced conjugated polymers and small molecules for next-generation electronic materials. It is primarily sought by R&D and production teams in the organic electronics, photovoltaics, and semiconductor industries who require reliable, high-quality building blocks for precise molecular engineering.

Application

• Organic Photovoltaic (OPV) Cells: Serves as a key monomer in the synthesis of donor-acceptor (D-A) conjugated polymers for high-efficiency solar cell active layers.
• Organic Field-Effect Transistors (OFETs): Used to create semiconducting polymers with tailored energy levels and charge carrier mobility for flexible electronics.
• Polymer Synthesis via Suzuki Cross-Coupling: The pinacol boronate ester groups enable efficient, palladium-catalyzed polymerization reactions to construct well-defined polymer backbones.
• Electrochromic Devices: A precursor for polymers that change color in response to an electrical stimulus, used in smart windows and displays.
• Chemical Sensing Materials: Incorporated into polymers designed for the selective detection of gases, ions, or biological molecules.
• Academic and Industrial R&D: A fundamental building block for exploring new structure-property relationships in organic semiconductor materials.

Quality Control

Our production of this advanced monomer adheres to strict quality protocols to ensure batch-to-batch consistency critical for polymer performance. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and GC to verify chemical identity, purity, and the absence of critical metallic impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., argon or nitrogen) due to its moisture-sensitive nature. Allow the sealed container to equilibrate to room temperature before opening to minimize condensation and hydrolysis.
