一般說明

1′,3′-二氢-1′,3′,3′-三甲基-6-硝基螺(2 H -1-苯并吡喃-2,2′-(2 H )-吲哚)(硝基化合物)是一种光致变色的生物相容螺吡喃分子,在苯并吡喃部分有 6 个硝基。[1][2] [3] 它有一个无色的无色无色的无色螺环吡喃形式 (SP) 和有色的反式份菁形式 (MC),分别在紫外和可见光区呈现吸收峰。[4]与其他螺吡喃分子相比,硝基二苯醚具有更高的量子产率,并能溶于多种溶剂。[5][6]

應用

硝基聚苯硫醚 (NitroBIPS) 是一种光致变色染料,通过静电纺丝可与聚乙烯醇 (PVA) 形成 PVA-螺吡喃纳米纤维。它具有光响应行为,可用于光学数据存储应用。[7]它可以用来掺杂液晶,开发一种双响应的彩色散射装置,并允许电流体力学不稳定性 (EHDI) 的启动。加入 NitroBIPS 可以将透明度从 100% 提高到 16%,提供了屏蔽效果,可用于智能窗口应用。[8]它也可以通过提高剪切强度 7 倍来提高聚苯乙烯 (PS) 在玻璃基板上的粘接性能。[9]

Questions

1–2 of 2 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
