This study reveals how the morphology of organic mixed ionic-electronic conductors (OMIECs) controls the mixed ionic-electronic transport of organic electrochemical transistors (OECTs). Two p-type OMIECs with oligoethylene glycol (OEG) side chains, namely P3MEEET and P3MEEMT, are blended with polystyrene (PS) to produce laterally phase-separated morphologies. By varying the ratio between OMIEC and PS, distinct morphologies […]
