Description

Stannane, 1,1'-[4,8-Bis[4-[(2-Ethylhexyl)Thio]Phenyl]Benzo[1,2-B:4,5-B']Dithiophene-2,6-Diyl]Bis[1,1,1-Trimethyl- is a high-purity, organotin-functionalized organic semiconductor material. This compound is engineered as a critical p-type dopant and hole-transport material for enhancing the performance and stability of next-generation electronic devices. It is primarily required by R&D laboratories and manufacturers in the organic electronics and photovoltaics sectors.

Application

• Organic Photovoltaic (OPV) Cells: As a p-type dopant in the hole transport layer (HTL) to improve conductivity, charge extraction, and overall power conversion efficiency.
• Perovskite Solar Cells: Used in hole-transporting materials (HTMs) to enhance device stability and reduce hysteresis.
• Organic Light-Emitting Diodes (OLEDs): Employed as a doping agent in hole injection and transport layers to lower operating voltage and increase device longevity.
• Organic Field-Effect Transistors (OFETs): Functions as a molecular dopant to precisely tune the charge carrier concentration and mobility in the semiconductor channel.
• Advanced Material Research: Serves as a key building block for synthesizing novel conjugated polymers and small molecules with tailored electronic properties.
• Printed Electronics: Suitable for solution-processable formulations used in inkjet printing or slot-die coating for large-area, flexible electronics.

Quality Control

Every batch of our high-value electronic chemicals undergoes rigorous analytical characterization to ensure consistency and performance. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and critical impurity profiles. Our quality system is designed to support advanced materials research and pilot-scale production, with traceability and documentation meeting high R&D standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label. The material is moisture-sensitive and easily oxidized; ensure containers are sealed immediately after use to minimize exposure to air and humidity. Keep away from heat and incompatible materials.
