General description

Poly(3-hexylthiophene-2,5-diyl) (P3HT) is a polythiophene-based low bandgap semiconducting polymer. It is widely used as anelectron donor material in organic solar cells, OLEDs, and OFETs due to itschemical and thermal stability, controlled synthetic method, goodsemiconducting properties, simple structure, and widecommercial availability. The degree of regioregularity of P3HT has a stronginfluence on its ability to form highly ordered domains.

Application

Poly(3-hexylthiophene-2,5-diyl) can be used as a:

  • Active semiconductor to prepare organic field emission transistors. In regioregular P3HT the microcrystalline domains are well constructed by phase-segregated layers of insulating alkali side chains and pi-pi interchain stacking. This leads to high charge mobility and enhances the performance of OFETs.
  • Precursor to synthesize P3HT-PCBM( [6,6]-phenyl C61-butyric acid methyl ester) blend thin film. The highcrystallinity of P3HT thin film increases the efficiency of organicphotovoltaic cells.

This report focuses on the synthesis of novel 2,3,4,5-tetrathienylthiophene-co-poly(3-hexylthiophene-2,5-diyl) (TTT-co-P3HT) as a donor material for organic solar cells (OSCs). The properties of the synthesized TTT-co-P3HT were compared with those of poly(3-hexylthiophene-2,5-diyl (P3HT). The structure of TTT-co-P3HT was studied using nuclear

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.
