What is it about?
A hybrid acceptor-modulation strategy is demonstrated based on diketopyrrolopyrrole (DPP)-containing fluorinated triple-acceptor architecture (DFB). Therefore, the DFB-based polymers features low-lying frontier molecular orbital enengy levels, shape-persistent backbones, and high crystallinity. The above features lead to an electron mobility of 5.04 cm2 V−1 s−1 in unipolar n-type transistors, which is the highest electron mobility for DPP-based unipolar n-type semiconducting polymers reported to date.
