aCalculated from inductively coupled plasma mass spectrometry (ICP-MS, detailed in the SI).

bOECT mobility calculated from the transistor saturation µC* product using the respective C* values.

cC* values extracted from Randles circuit fits from electrochemical impedance curves of the polymers coated on Au electrodes in 0.1 M aqueous NaCl solution.

d[μC*] calculated for the highest performing channel from the slope of gm with known channel dimensions and applied bias.

ePeak OECT transconductance normalized by thickness.

fFormed by combining a mass ratio of 1:1.32:0.16:1 of F1:F2:F3:F4 for p(g4T2-TT), which resulted in Mn = 90.6 kDa and a mass ratio of 1:1.4:1.4:1 of F1:F2:F3:F4 for p(C6g3NDI-T), which resulted in Mn = 61.2 kDa. All measurements are an average across 6 devices.
