一般描述

MEH-PPV是一种具有低分子量和疏水特性的导电有机半导体。它是一种聚（亚苯基亚乙烯基）（PPV）衍生物，是在金的费米能级以下具有最高占据分子轨道（HOMO）的一种共轭聚合物。
发光共轭聚合物。

应用

有机半导体激光材料
MEH-PPV可通过旋涂与碳纳米管（CNT）形成纳米复合材料，该复合材料可用于H2S气体传感器。它也可以用作导电聚合物，从而形成低成本的无掺杂空穴传输材料（HTM），用于制造钙钛矿型太阳能电池，功率效率可达到9.65％。MEH-PPV可与PCPDTBT混合，用作染料敏化光传感器（DSPS）的敏化剂。

  4. 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. 

  5. 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.

  6. 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.

  7. 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).

  8. Does Product 541443, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene], contain a dopant?

    This product does not contain a dopant.
