General description

MEH-PPV is a conducting organic semiconductor which has low molecular weight and hydrophobic characteristics. It is a poly(phenylenevinylene) (PPV) derivative and a conjugating polymer with highest occupied molecular orbital (HOMO) below the fermi level of gold.
Light-emitting conjugated polymer.

Application

Conducting polymer in solar cells and carbon nanotube OLEDs. Useful in producing bright and efficient white polymeric light emitting diodes.
Filter before application.
MEH-PPV can form a nanocomposite with carbon nanotubes (CNTs) by spin coating that can be used for H2S gas sensors. It can also be used as a conducting polymer which results in the formation of a low-cost dopant free hole transporting material (HTM) for the fabrication of perovskite solar cells with a power efficiency of 9.65%. MEH-PPV can be blended with PCPDTBT for use as a sensitizer for dye sensitized photo sensors (DSPS).
