PDPPs showing high cycling stability and cell viability for OECTs

A comprehensive investigation of four polydiketopyrrolopyrroles (PDPPs) with increasing ethylene glycol (EG) content and varying nature of comonomer is studied, and guidelines for the design of efficient mixed ion‐electron conductors (MIECs) are published in Adv. Funct. mater. 2021. A considerable cycling stability for 1200 cycles and an outstanding cell compatibility render these PDPPs as viable candidates for in vitro and in vivo bioelectronics.
