Tuning transport via interaction strength in cationic conjugated polyelectrolytes

This data set accompanies the article \"Tuning transport via interaction strength in cationic conjugated polyelectrolytes\" published in Macromolecules in 2023 (10.1021/acs.macromol.3c01206). The article studies structure-property relationships for mixed lithium-electron conduction in organic polymers, emphasizing the importance of polymer-ion interaction strength.
This data set contains comprehensive characterization information- including ionic conductivity via electrochemical impedance spectroscopy (EIS), DC polarization, NMR Relaxometry, UV-Vis spectroscopy, electronic conductivity, and wide angle x-ray scattering. Data is presented in non-proprietary text, CSV, and TIF formats. Technique and sample identification is contained in the file titles, which correspond to figure numbers. Every column in each data file contains a header indicating the data that was recorded and the unit in which it was recorded. , Ionic Conductivity
Ionic conductivity samples were prepared by first dissolving the appropriate amount of polymer in 50/50 methanol/acetonitrile for P3HT-Im+TFSI– and P3HT-TMA+TFSI–. It was found that 80/20 methanol/water was ideal for P3HT-NH3+TFSI–. LiTFSI/methanol solution was added to achieve the desired salt concentrations, and solutions were thoroughly mixed. The polymer/salt solution was then drop cast onto clean circular indium tin oxide (ITO) substrates top-coated with a 150 μm Kapton spacer in which a well of known diameter was punched. The samples were sealed with clean ITO substrates and dried under high vacuum (2 × 10–8 torr) at 115°C for 12 hours. Samples were then loaded into an argon glovebox and loaded into a Controlled Environment Sample Holder (CESH) from Biologic LLC, which maintains an inert atmosphere during measurement. Variable temperature conductivity measurements were performed using Biologic’s Intermediate Temperature System (ITS) in conjunction with their VS...,
