General description

6,13-Bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) is a conductive polymer that can form organic thin films for a variety of semiconductor applications due to its high charge carrier mobility and stability.

Application

TIPS Pentacene is a high-performance soluble organic semiconductor for printed and flexible electronics applications. Material Matters™ 4.3 - Organic and Molecular Electronics Examples include the fabrication of organic field effect transistors (OFETs) with the highest reported switching speeds and field-effect mobilities in its class.
Silyethyne-Substituted Pentacenes
TIPS-pentacene forms a hybrid with (6,6)-phenylC61-butyric acid methyl ester (PCBM) which can be used as an organic layer that can be coated onto a silicon (Si) substrate for the fabrication of a highly efficient terahertz (THz) modulator. It can be used as a piezoresisitive sensor that produces multiple strain sensors (single sensors and sensor arrays). Organic thin-film transistors can be developed by using silver electrodes as dielectric materials and TIPS-pentacene as a semiconducting layer, which can be deposited via inkjet printing.

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/418/501/product-dating-information-06-25-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
