General description

1-Octadecene is a long-chain hydrocarbon used in the synthesis of nanoparticles as a capping and reducing agent.[1]

Application

1-Octadecene has been commonly used as a non-coordinating solvent for growing nanoparticles and quantum dots due to its high boiling point.[2][3][4] The 1-octadecene monolayer is a promising passivating coating in nanoelectronics due to its stability and chemical protection against oxidation, effects of acids and bases without altering the properties.[5]

Other Notes

Contains 2-octyl-1-decene, n-octadecane, 2-butyl-1-tetradecene, 2-hexyl-1-dodecene

All-inorganic CsPbX3 (X = Cl, Br, and I) perovskite quantum dots (PeQDs) have shown great promise in optoelectronics and photovoltaics owing to their outstanding linear optical properties; however, nonlinear upconversion is limited by the small cross-section of multiphoton absorption, necessitating high power

  1. What is the recommended storage temperature for this 1-octadecene?

    1 answer

    1. This product may be stored at room temperature.

      Helpful?

  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.

  3. 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
