Description

General description

MDMO-PPV is a dialkoxy substituted poly(p-phenylenevinylene) (PPV) based conjugating polymer which has long side chains that form flexible films for organic electronics. It is a piezoresistant polymer with HOMO and LUMO orbital positions at 5.4 and 3.4 eV, respectively. MDMO-PPV forms an active layer that can be used in photoconductive and electroluminescent applications.[1][2][3] Its processability and film-forming properties are superior to MEH-PPV.[4]

Application

MDMO-PPV can also be used in the fabrication of bulk heterojunction solar cells(BHJ).[5][6]

MDMO-PPV can be blended with (6,6 phenyl C61- butyric acid methyl ester) (PCBM), which can be coated on indium tin oxide (ITO) to fabricate polymeric solar cells.[7][8][9] It can also be used as a red light emitting polymer (LEP), which can be used in the fabrication of red-green-blue laser-based polymeric membranes.[10]
