Description

(5,10-Didodecylnaphtho[1,2-B:5,6-B']Dithiophene-2,7-Diyl)Bis(Trimethylstannane) is a high-purity, functionalized organic semiconductor building block, specifically a stannylated naphthodithiophene derivative. This compound matters as a critical precursor in the synthesis of advanced conjugated polymers and small molecules via Stille cross-coupling polymerization. It is primarily needed by R&D and production teams in the organic electronics sector for developing high-performance materials for next-generation devices.

Application

• Organic Field-Effect Transistors (OFETs): As a key monomer for synthesizing p-type semiconductor polymers with high hole mobility.
• Organic Photovoltaics (OPVs / Solar Cells): Used in the construction of donor-acceptor copolymer backbones for efficient bulk-heterojunction solar cells.
• Organic Light-Emitting Diodes (OLEDs): Serves as a building block for host or emissive layer materials, particularly for red and near-infrared emission.
• Perovskite Solar Cells: Employed in the synthesis of novel hole-transporting materials (HTMs) to improve device stability and efficiency.
• Chemical Sensors: Used to create conjugated polymers with tailored electronic properties for detecting specific analytes.
• Academic & Industrial R&D: A fundamental reagent for exploring new organic semiconductor architectures and structure-property relationships.

Quality Control

Every batch of our (5,10-Didodecylnaphtho[1,2-B:5,6-B']Dithiophene-2,7-Diyl)Bis(Trimethylstannane) is synthesized and purified under inert atmosphere to ensure maximum stability and reactivity. We employ advanced analytical techniques including NMR (1H, 13C, 119Sn) and HPLC to verify chemical identity and high purity, which is critical for reproducible Stille polymerization results. Certificates of Analysis (COA) with full characterization data are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store the product in a freezer at -20°C to -10°C under an inert atmosphere (argon or nitrogen). Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation. The material is light-sensitive and should be handled in a glovebox or under a nitrogen atmosphere when possible.
