Chemical Structure

Chemical Structure of MEH-PPV, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]; CAS No. 138184-36-8; Chemical Formula (C18H28O2)n.

Applications

Poly[2-methoxy-5-(2’-ethylhexyloxy)-1,4- phenylene vinylene] (MEH-PPV) is a PPV derivative that is particularly favourable for device fabrication due to its great solubility in most of the common organic solvents owing to its asymmetric side chains. To date, MEH-PPV is possibly one of the most celebrated and studied polymer semiconductors, recognising its applications in OPV, OFETs, polymer light-emitting diodes (PLED) and perovskite solar cells.

The first example of a polymer solar cell with a convincing understanding of the physics and chemistry involved was the bilayer heterojunction cell utilising the soluble polymer MEH-PPV and the Buckminsterfullerene C60 where a power conversion efficiency of 0.04% was obtained using monochromatic light.[1, 2]
