Description

4,4'-((1E,1'E)-(2,5-Dimethoxy-1,4-Phenylene)Bis(Ethene-2,1-Diyl))Dibenzonitrile is a high-purity, conjugated organic compound featuring a central dimethoxyphenylene core symmetrically linked to benzonitrile groups via ethenylene bridges. This molecular architecture is critical for applications requiring strong electron-accepting properties and excellent charge transport characteristics. It is primarily sought after by researchers and manufacturers in the advanced materials and pharmaceutical intermediates sectors.

Application

• As a key electron-transport material (ETM) or non-fullerene acceptor (NFA) in the active layer of organic photovoltaic (OPV) cells and perovskite solar cells.
• As a building block for organic semiconductors used in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs).
• In the synthesis of advanced conjugated polymers and small molecules for optoelectronic research and development.
• As a fluorescent probe or tag in biochemical sensing and imaging applications due to its potential luminescent properties.
• As a specialty intermediate in pharmaceutical research for constructing complex, rigid molecular frameworks.
• In materials science research for developing liquid crystals or other functional materials with tailored electronic properties.
