General description

Light-emitting conjugated polymer.
Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) is a highly efficient conjugated polymer known for its exceptional optical and electronic properties. This polymer is widely utilized in organic electronics, particularly in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). With an average molecular weight of 40,000-70,000, MEH-PPV exhibits a band gap of 2.3 eV and emits a vibrant orange-red light with a maximum emission wavelength of 554 nm. Its hydrophobic characteristics and good solubility in organic solvents make it suitable for various applications, including flexible displays and sensors.

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).

Features and Benefits

  • High Molecular Weight: Average Mn of 40,000-70,000, providing robust mechanical properties and stability.
  • Optical Properties: Band gap of 2.3 eV with fluorescence emission at em 554 nm when excited at λmax 493 nm in toluene.
  • Charge Transport: HOMO of -5.3 eV and LUMO of -3 eV, facilitating effective charge transport in electronic applications.
  • OLED Performance: Proven performance in OLED devices, achieving maximum luminance of 1,400 Cd/m2 and external quantum efficiency up to 2.5%.
  • Storage Conditions: Recommended storage at 2-8°C to maintain product integrity.
