Description

4,9-Bis(5-Bromo-2-Thienyl)-2,7-Bis(2-Octyldodecyl)-Benzo[Lmn][3,8]Phenanthroline-1,3,6,8(2H,7H)-Tetrone is a high-purity, functionalized organic semiconductor material belonging to the naphthalene diimide (NDI) derivative family. This compound matters for its excellent electron-accepting properties, high electron mobility, and good solution processability, which are critical for advanced electronic device performance. It is primarily needed by researchers and manufacturers in the organic electronics sector, particularly for developing next-generation organic field-effect transistors (OFETs), organic photovoltaics (OPVs), and perovskite solar cells.

Application

• Key electron-accepting component (n-type semiconductor) in Organic Field-Effect Transistors (OFETs) for flexible displays and logic circuits.
• Electron transport layer (ETL) or non-fullerene acceptor material in Organic Photovoltaic (OPV) cells and Perovskite Solar Cells to enhance power conversion efficiency.
• Active layer material for organic photodetectors and image sensors.
• Building block for synthesizing more complex polymer semiconductors and small molecule acceptors via further cross-coupling reactions.
• Used in academic and industrial R&D for studying structure-property relationships in n-type organic semiconductors.
• Potential use in organic light-emitting transistors (OLETs) and other emerging optoelectronic devices.
