There has been tremendous progress in the synthesis and development of π-conjugated polymer semiconductors for diverse applications in electronics and photonics in the last two decades. Advances in the synthesis of diverse p-type polymers have enabled the development of high-performance organic field-effect transistors (OFETs) as well as more efficient fullerene-based organic photovoltaics (OPVs). In contrast, n-type polymer semiconductors remain relatively scarce and the performance of n-channel OFETs has consequently lagged significantly behind those of p-channel OFETs. Similarly, the performance of all-polymer (polymer/polymer bulk heterojunction) solar cells has lagged far behind those of fullerene-based OPVs. Thus, the development of suitable n-type polymer semiconductors is of great interest in the fields of organic electronics and OPVs. |
