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。[1][2][3]
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。[4]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％。[5]MEH-PPV可与PCPDTBT混合，用作染料敏化光传感器（DSPS）的敏化剂。[6]

Questions

1–8 of 8 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  8. Can Product 541443, Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene], efficiently convert light to electricity?

    1 answer

    1. 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).
