Description

4,8-Diyldi-5,2-Thiophenediylbis[4-(N,n-Bis(4-Octyloxyphenyl)Amino)Phenyl][1,2,5]Selenadiazolo[3,4-F]-2,1,3-Benzothiadiazole is a high-performance organic semiconductor material belonging to the class of donor-acceptor (D-A) conjugated polymers. This compound matters for its exceptional optoelectronic properties, including a narrow bandgap and strong absorption in the near-infrared (NIR) region, making it a critical component in advanced electronic devices. It is primarily needed by researchers and manufacturers in the fields of organic photovoltaics (OPVs), organic field-effect transistors (OFETs), and photodetectors for next-generation flexible and printed electronics.

Application

• Active layer material in organic solar cells (OSCs) and perovskite solar cells for enhanced light absorption and power conversion efficiency.
• Semiconducting channel material in organic field-effect transistors (OFETs) for flexible displays and logic circuits.
• Key component in near-infrared (NIR) photodetectors and image sensors for telecommunications and medical imaging.
• Used in organic light-emitting transistors (OLETs) and other novel electro-optic devices.
• As a hole-transport material (HTM) or electron donor in multilayer optoelectronic device architectures.
• Fundamental research on structure-property relationships in D-A conjugated polymers and small molecules.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is light-sensitive (store away from light) and should be handled under an inert atmosphere when possible to prevent degradation. Keep the container tightly sealed in a desiccator to minimize exposure to moisture and oxygen.
