Description

5,10-Bis((5-Octylthiophen-2-Yl)Dithieno[2,3-D:2′,3′-D′]Benzo[1,2-B:4,5-B′]Dithiophene-2,7-Diyl)Bis(Trimethylstannane) is a high-purity, functionalized organic semiconductor building block, specifically designed as a key monomer for advanced polymer synthesis. Its complex, fused-ring structure with electron-rich thiophene and dithienobenzodithiophene units is engineered to deliver superior charge transport properties in optoelectronic devices. This compound is essential for researchers and manufacturers developing next-generation organic photovoltaics (OPVs), perovskite solar cells, and organic field-effect transistors (OFETs).

Application

• Polymer Donor Material Synthesis: Serves as the critical core monomer for constructing high-performance, low-bandgap conjugated polymers used in bulk heterojunction organic solar cells.
• Perovskite Solar Cell (PSC) Hole-Transport Layers (HTLs): Used to synthesize polymeric HTL materials that enhance device stability and power conversion efficiency.
• Organic Field-Effect Transistor (OFET) Fabrication: A precursor for semiconducting polymers that form the active channel layer in OFETs, enabling high charge carrier mobility.
• Organic Photodetectors (OPDs): Employed in the development of polymer-based photodetectors for sensing and imaging applications.
• Research & Development: A vital reagent for academic and industrial R&D focused on novel organic electronic materials and device architectures.
• Stille Polycondensation Reactions: Functions as a bis-stannylated monomer in palladium-catalyzed cross-coupling polymerizations to create well-defined, high-molecular-weight conjugated polymers.

Quality Control

Our production of this advanced material adheres to strict quality control protocols to ensure batch-to-batch consistency and high purity, which are critical for reproducible device performance. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with every shipment to support your R&D and manufacturing quality systems.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), it is recommended to store the product under an inert gas (argon or nitrogen) in a freezer at -20°C to -10°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
