Abstract

Conjugated rod‐coil block copolymers provide a promising route to decouple the optimisation of ionic and electronic transport in organic electrochemical transistors (OECTs). Poly(3‐alkoxythiophene) (P3AOT)‐based rod‐coil block copolymers with precisely tuned polyethylene glycol (PEG), and poly(L‐lactide) (PLLA) coil blocks are synthesised through a modular approach combining Kumada coupling transfer polymerisation (KCTP) and Knoevenagel condensation. An evaluation of the thin film morphology and subsequent OECT performance of a range of rod‐coil copolymers reveals that device performance can be enhanced compared to the corresponding homopolymer, establishing rod‐coil block copolymers as a versatile material platform and providing fundamental insight for the use of block copolymer in OECTs.
