Schmode, Philip;Hochgesang, Adrian;Goel, Mahima;Meichsner, Florian;Mohanraj, John;Fried, Martina;Thelakkat, Mukundan published 《A Solution-Processable Pristine PEDOT Exhibiting Excellent Conductivity, Charge Carrier Mobility, and Thermal Stability in the Doped State》 in 2021. The article was appeared in 《Macromolecular Chemistry and Physics》. They have made some progress in their research.COA of Formula: C16H34O The article mentions the following:
PEDOT:PSS [poly(3,4-ethylenedioxythiophene) polystyrene sulfonate] is a widely used insoluble conducting polymer, which is therefore processed from dispersions. In this work, PEDOT homopolymers (PEDOT-C6C8 1 and 2) highly soluble in common solvents like toluene, THF, and chloroform are synthesized with a high control of mol. weight and low dispersity using Kumada catalyst transfer polymerization of a newly synthesized EDOT monomer carrying a branched alkyl substituent. Pristine PEDOT-C6C8 allows the use in accumulation mode transistors with a high charge carrier mobility of 5 x 10-4 cm2 V-1 s-1. Moreover, these polymers can be doped in a controlled fashion, reaching conductivities of 10-3 S cm-1 at 10 mol% of a dopant, Spiro-MeOTAD(TFSI)2. The doped state is remarkably stable, retaining 80% of the initial value after annealing under nitrogen at 100 °C and being exposed to ambient atm. for up to 12 h. During doping, the hole injection barrier decreases and reaches an impressively low value of 130 meV at only 2.5 mol% dopant loading without loss in carrier mobility; as monitored using UV photoelectron- and impedance spectroscopy. This new design concept leading to highly soluble polymers with well-controlled mol. weights provides solution-processable PEDOT dopable in a well-controlled fashion. And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.
2-Hexyl-1-decanol(cas: 2425-77-6) has been shown to inhibit the growth of b16 mouse melanoma cells, suggesting it may be useful for treating skin cancer.COA of Formula: C16H34O This fatty acid also has transport properties and can form hydrogen bonds with other molecules.
