Description

2,2'-(4,8-Bis(5-(2-Ethylhexyl)Thiophen-2-Yl)Benzo[1,2-B:4,5-B']Dithiophene-2,6-Diyl)Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane) is a high-purity, advanced organic electronic material belonging to the class of conjugated polymers and small molecules. This compound is a critical building block (monomer) for synthesizing donor-acceptor copolymers used in next-generation organic photovoltaics (OPVs) and field-effect transistors (OFETs). It is essential for researchers and manufacturers in the organic electronics and renewable energy sectors who require reliable, high-performance materials to develop efficient and flexible electronic devices.

Application

• Organic Photovoltaic (OPV) Cells: Serves as a key electron-donor monomer for synthesizing low-bandgap polymers used in the active layer of solar cells to enhance light absorption and power conversion efficiency.
• Organic Field-Effect Transistors (OFETs): Used as a precursor for creating semiconducting polymers that form the channel material, crucial for developing flexible displays and sensors.
• Perovskite Solar Cells: Employed in the development of hole-transporting materials (HTMs) or interfacial layers to improve device stability and performance.
• Organic Light-Emitting Diodes (OLEDs): Can be utilized in the synthesis of host or emissive materials for specific color emission or charge transport layers.
• Chemical Research & Development: Acts as a fundamental boronic ester pinacol reagent for Suzuki-Miyaura cross-coupling reactions, enabling the precise construction of complex π-conjugated systems.
• Advanced Material Synthesis: A critical raw material for creating novel conjugated polymers and small molecules with tailored optical and electronic properties for cutting-edge applications.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is between -20°C to 0°C to maintain stability. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
