Polyterrylenes: synthesis and regioregularity effect on p-type charge transport and deep-red light photodetection in OFETs.

ABSTRACT: Polymers of higher rylene dyes remain largely unexplored despite their promising photophysical properties, due to the synthetic challenges and poor solubility, in contrast to their well-studied lower homologs, perylene and naphthalene derivatives. In this study, we report the first synthesis of terrylene-based regioregular and regioirregular homopolymers, namely rr-Polyterrylene and ri-Polyterrylene, respectively. Selective bromination of our previously synthesized 7,8-bis(hexadecyloxy)terrylene (TER-C16) furnished the corresponding dibromoterrylene. Then, Ni(0)-mediated Yamamoto homocoupling reaction produced the first soluble terrylene-based homopolymers. Both polymers achieved high solubility, high thermal stability, alongside very high molecular weight. Owing to these pro
