Description

2,1,3-Benzothiadiazole, 5,6-Difluoro-4,7-Bis[4-Hexyl-5-(Trimethylstannyl)-2-Thienyl]- is a high-value, organotin-functionalized benzothiadiazole derivative designed for advanced materials research and development. This compound is engineered as a critical building block (monomer) for synthesizing novel low-bandgap conjugated polymers and small molecules. It is essential for researchers and manufacturers in the organic electronics sector, particularly for developing next-generation organic photovoltaics (OPVs), field-effect transistors (OFETs), and photodetectors, where precise molecular control over energy levels and film morphology is paramount.

Application

• Organic Photovoltaic (OPV) Materials: Serves as a key electron-accepting unit in donor-acceptor (D-A) type conjugated polymers for high-efficiency solar cells.
• Organic Field-Effect Transistors (OFETs): Used in the synthesis of semiconducting polymers for high-mobility electronic devices.
• Organic Photodetectors (OPDs): A precursor for creating narrow-bandgap materials sensitive to specific wavelengths of light.
• Polymer Synthesis via Stille Coupling: The trimethylstannyl groups make it an ideal monomer for palladium-catalyzed cross-coupling reactions, enabling precise polymer chain growth.
• Advanced Material Research: Fundamental research into the structure-property relationships of novel organic semiconductors.
• OLEDs & Perovskite Solar Cells: Potential use as an intermediate or additive in the development of other optoelectronic layers.

Quality Control

This high-purity specialty chemical is produced under strict inert atmosphere conditions to ensure integrity. Each batch undergoes comprehensive analytical characterization, including NMR (1H, 13C, 19F) and HPLC to confirm chemical structure and purity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. Our quality management system supports cGMP and ISO 9001 standards for traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C or as specified on the label. This compound is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Allow the sealed container to reach room temperature before opening to prevent moisture condensation. Keep away from strong acids and oxidizing agents.
