摘要：
We have found that 9,9'BF can be used as an electron acceptor for P3HT-based OPVs while similar devices using 4,4'BP do not show any photovoltaic effect. This can be related to the respective aromaticity and antiaromaticity of the reduced forms of 9,9'BF or 4,4'BP. The OPV device fabricated using P3HT and 9,9'BF exhibited a PCE of 2.28% with a V-oc of 1.07 V, a J(sc) of 5.04 mA cm(-2), and a FF of 0.42.
