Poly(diketopyrrolopyrrole-terthiophene) for Ambipolar Logic and Photovoltaics

摘要

Polymers based on diketopyrrolopyrrole (DPP) have been known for a relatively long time but are only recently emerging as promising candidates for use in optoelectronic applications, particularly in field-effect transistors (FETs) and organic photovoltaic cells (OPCs). OPC efficiencies up to 4.45% have been reached with DPP polymers and oligomers. Here we present a new DPP based polymer, PDPP3T (Figure 1), that features high, almost balanced charge carrier mobilities for both electrons and holes in combination with an extended optical absorption toward the IR region.
