a Typical n-type OECT transfer characteristics of 2DPP-OD-TEG OECTs measured in 0.1 M aqueous solutions of chloride salts with different cations as mentioned in the plot legend. b Box plot showing ID,max measured for identical OECTs for insertion of different cations along with plot of mean ID,max as a function of the ionic radius of the respective inserted cation. Error bars represent standard deviation. c Five cycles of CV at a scan rate of 100 mV/s in electrolytes containing each of the four cations. d Volumetric capacitance, C*eff estimated from EIS for different cations. For the box plots, center line is median; box limits are 25th and 75th percentiles; whiskers are outliers within 25th and 75th percentile + 1.5x interquartile range; ‘□’ represents mean value; ‘⨯’ represents maximum and minimum values.
