| 英文摘要 | Three novel asymmetric thiophene/benzothiophene-flanked diketopyrrolopyrrole (DPP)-based polymers with different p bridges, designated as PBTTDPP-BT, PBTTDPP-TT and PBTTDPP-2FBT, were designed, synthesized and employed in organic solar cells. Compared with the reported thiophene/pyridine-flanked DPP, these thiophene/benzothiophene-flanked DPP polymers exhibited narrower band gaps below 1.5 eV, leading to a broadened absorption that ranged from 500 nm to 850 nm. All polymers displayed promising ambipolar semiconducting properties. PBTTDPP-BT, PBTTDPP-TT and PBTTDPP-2FBT showed hole mobilities of 1.20, 1.68 and 1.50 cm(2) V-1 s(-1), respectively. Their corresponding electron mobilities were 0.40, 0.14 and 0.35 cm(2) V-1 s(-1). Interestingly, PBTTDPP-TT and PBTTDPP-2FBT also showed ambipolar properties in organic solar cells. Photovoltaic device based on PBTTDPP-TT as a donor material reached a power conversion efficiency (PCE) of 6.96% with PC71BM as an acceptor, while this device as the acceptor material achieved only 0.28% with poly(3-hexylthiophene) (P3HT) as the donor. In contrast, PCE of PBTTDPP-2FBT-based devices reached 5.62% with PC71BM and 0.44% with P3HT. These results suggest that the adoption of asymmetric flankers in DPP polymers can effectively tune their ambipolar transporting properties for high-performance organic electronic devices. |
