Description

In1537, 7-Bromo-4,4,9,9-Tetrahexyl-4,9-Dihydro-S-Indaceno[1,2-B:5,6-B']Dithiophene-2-Carbaldehyde is a high-purity, functionalized organic semiconductor building block. This compound is critical for the synthesis of advanced organic electronic materials due to its specific electron-accepting and light-absorbing properties. It is primarily required by R&D and production teams in the organic photovoltaics (OPV), organic light-emitting diodes (OLED), and organic field-effect transistor (OFET) sectors.

Application

• Organic Photovoltaic (OPV) Materials: Serves as a key electron-acceptor or intermediate in the synthesis of non-fullerene acceptors (NFAs) for high-efficiency solar cells.
• Organic Light-Emitting Diodes (OLED): Used in the development of novel emitters or host materials for display and lighting technologies.
• Organic Field-Effect Transistors (OFET): Acts as a precursor for p-type or n-type semiconductor molecules in thin-film transistors.
• Chemical Synthesis & Research: A versatile intermediate for academic and industrial research in conjugated polymer and small molecule chemistry.
• Perovskite Solar Cells: Investigated as a component in hole-transporting layers or as an additive to improve device stability and performance.
• Photodetectors & Sensors: Employed in the fabrication of light-sensitive organic electronic devices for sensing applications.
