Description

In1588, 2,6-Bis(Trimethylstannyl)Thieno[2',3':4,5]Thieno[3,2-B]Thieno[2,3-D]Thiophene is a high-purity, organotin-functionalized fused thiophene derivative, serving as a critical advanced organic semiconductor building block. Its unique molecular architecture enables precise tuning of electronic properties in conjugated materials. This compound is essential for R&D and production in organic electronics, particularly for developing next-generation electronic devices.

Application

• Organic Thin-Film Transistors (OTFTs): As a key precursor for p-type semiconductor polymers and small molecules.
• Organic Photovoltaics (OPVs/Perovskite Solar Cells): Used in the synthesis of donor or acceptor materials to enhance light absorption and charge carrier mobility.
• Organic Light-Emitting Diodes (OLEDs): Serves as a monomer for constructing emissive or charge-transport layers.
• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): Acts as a tin-containing precursor for depositing thin films of metal sulfides or doped semiconductor layers.
• Polymer & Material Science Research: A versatile reagent for Stille cross-coupling reactions to create complex, π-conjugated systems for electronic applications.
• Sensors and Bioelectronics: Used in developing conductive polymers for sensitive and selective detection platforms.

Quality Control

Every batch of In1588 is synthesized and purified under controlled conditions to ensure high chemical purity and lot-to-lot consistency, critical for reproducible device performance. Our quality system includes rigorous analysis via NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its moisture-sensitive (hygroscopic) nature, store under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage at 2-8°C to maintain stability. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
