一般描述

4,4′-bpy通常用于桥接金属中心以形成具有新特性的配位聚合物。[1]4,4′-bpy配体可通过稳定磁序来介导顺磁性金属离子之间的电子效应。[2]
4,4′-联吡啶(BPY)是一种主要用于制备配位聚合物的有机交联剂。它是一种吡啶衍生物,其中的吡啶基可以沿着碳碳结构旋转。它可以作为光电化学还原的催化剂。[3][4][5]

应用

4,4′-联吡啶(4,4′-联吡啶,4,4′-bpy)和Co(NCS)2 溶液相互扩散形成单晶Co(NCS)2(4,4′-bipy)2·2(CH3CH2)2O和Co(NCS)2(4,4′-bipy)2·2(CH3CH2)2O。[6]
BPY是一种配体,在过渡金属之间形成网络,从而形成配位键。[7]可通过配位聚合物和BPY作为复合连接剂制备杂化纳米片。[3]它由两个活性位点组成,可用于药物开发。[8]

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
