Two new glycolated semiconducting polymers, PgBT(F)2gT and PgBT(F)2gTT, with different backbone curvatures were designed and synthesised for application in p-type accumulation mode organic electrochemical transistors (OECTs). While PgBT(F)2gT achieved a higher volumetric capacitance due to its curved backbone geometry, PgBT(F)2gTT exhibited superior OECT performance overall thanks to its enhanced order, resulting in faster charge mobility.
Two new glycolated semiconducting polymers PgBT(F)2gT and PgBT(F)2gTT of differing backbone curvatures were designed and synthesised for application as p-type accumulation mode organic electrochemical transistor (OECT) materials. Both polymers demonstrated stable and reversible oxidation, accessible within the aqueous electrochemical window, to generate polaronic charge carriers. OECTs fabricated from PgBT(F)2gT featuring a curved backbone geometry attained a higher volumetric capacitance of 170 F cm(-3). However, PgBT(F)2gTT with a linear backbone displayed overall superior OECT performance with a normalised peak transconductance of 3.00x10(4) mS cm(-1), owing to its enhanced order, expediting the charge mobility to 0.931 cm(2) V-1 s(-1).
