Descripción general

3,4-Ethylenedioxythiophene (EDOT) is an electro-active conductive monomer with a thiol group that combines an electron donor and electron acceptor in a donor-acceptor-donor arrangement.[1]
Monomer used in the synthesis of conducting polymers.

Aplicación

EDOT can be polymerized to form poly(3,4-ethylenedioxythiophene) (PEDOT) for use as an electrochromic polymer (EC) based coating for a variety of applications like solid state organic electrochemical supercapacitors (OESCs),[2][3] electrochromic devices (ECDs),[1] and carbon nanotubes (CNTs) based electrochemical devices for diabetes monitoring.[4]
It can be used:
  • As a reductant in a one-pot synthesis of gold nanoparticles from HAuCl4 (254169).[5]
  • As a starting material used in palladium-catalyzed mono- and bis-arylation reactions.[6]
  • In the synthesis of conjugated polymers and copolymers, with potential optical applications.[7][8]

A motor-based microprobe is proposed using a tubular microengine powered by bio-assembled enzyme as catalyst and exploited for washing-free detection of DNA through motion readout. The microprobe is fabricated by assembling a catalase layer on the inner surface of poly(3,4-ethylenedioxythiophene)/Au

Preguntas

1–2 de 2 Preguntas  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 respuesta

    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 respuesta

    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
