Organic mixed ionic-electronic conductors (OMIECs), electric (semi-)conductors with the capacity to transport ionic species, can be used for a wide range of applications including biological sensors or organic electrochemical transistors (OECTs) for use in sensing and circuitry for neuromorphic devices. Our previous studies of blends of poly(3-hexylthiophene) (P3HT) and an ion conductive polymer suggest improved performance of semiconducting organic transistors over P3HT alone, potentially due to differences in ion conductivity and conformation. This finding suggests that random or block copolymers of these materials may lead to improvements of performance of different OECTs. The synthesis of a modified catalyst for the graft through synthesis of oxanorbornene dicarboximide initiated P3HT to allow for the synthesis of these random or block copolymers in order to effectively compare these copolymers to polymer blends.
