| 英文摘要 | Three novel linear-shape small molecules of TPA(DPP-PN)(2), Cz(DPP-PN)(2) and Fl(DPP-PN)(2) were synthesized and characterized, which contain the same arm of diketopyrrolopyrrole (DPP) and large aryl terminals of phenanthrene (PN), as well as different aryl centers of triphenylamine( TPA), carbazole (Cz) and fluorene (Fl), respectively. Narrower optical band gaps (1.62-1.69 eV) and lower highest occupied molecular orbital energy levels (-5.71 to -5.79 eV) were observed in these small molecules compared with those corresponding values of the analogues without the PN terminal. Furthermore, the Cz(DPP-PN)(2) and Fl(DPP-PN)(2) molecules with planar centers exhibited better photovoltaic performance than the TPA(DPP-PN)(2) with a non-planar center in the solution-processed organic solar cells using [6,6]-phenyl-C61-butyric acid methyl ester as acceptor. The highest power conversion efficiency of 4.13% and a short-circuit current density of 8.77 mA cm(-2) were obtained in the Fl(DPP-PN)(2) based cell. It indicates that introducing large planar aryl groups as molecular center and terminals is an efficient strategy to improve absorption and photovoltaic performances in their linear-shape A-D-A-type small molecules.
