Description

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

Organic Semiconductor Laser Materials

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).

What is the Department of Transportation shipping information for this product?
Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
What is the solubility of Product 541443, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]?
Per our quality control testing, this product is soluble in toluene with heat and sonication at a concentration of 0.02 g/L.
What is the glass transition temperature (Tg) of Product 541443, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]?
Unfortunately, the glass transition temperature (Tg) is not determined for this product.
Can Product 541443, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene], efficiently convert light to electricity?
The polyphenylenevinylene (PPV) polymers themselves do not convert light to electricity very efficiently.They need to be blended with an electron transport material. The best material for this is a fullerene material called [6,6]-Phenyl C61 butyric acid methyl ester (PCBM, offered as #684430, 684449, 684457). There are several references that discuss polymer-fullerene heterojunctions.One paper on this subject is Brabec, C.J.; et. al. Applied Physics Letters, 80, 1288 (2002).
Does Product 541443, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene], contain a dopant?
This product does not contain a dopant.
