General description

Dichlorodiphenylsilane is a silane based surface modifier, and a precursor which can be used in the synthesis of silica based materials. It is used to modify the surface by providing toughness, durability and resistance to shock.[1][2]

Application

Dichlorodiphenylsilane can be used in the synthesis of a host material for the fabrication of blue phosphorescent organic light emitting diodes (OLEDs).[3][4]
The addition reaction of dichlorodiphenylsilane with diglycidyl ether of bisphenol-S yields poly(silyl ether) with pendant chloromethyl groups. {40} The coupling reaction between dichloromethylsilane and dichlorodiphenylsilane can form diorganosilane-hydrosilane copolymers at -75oC. Heating the compound with tetrabutoxydianilinocyclophosphazene at temperatures between 100oC-160oC may yield cyclophosphazene oligomers.{42}

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
