| 英文摘要 | Perylenediimide (PDI) possesses intense absorption, a low-lying energy level, and a high electron mobility. However, its highly planar conformation and thus strong intermolecular pi-pi stacking prevents its application as an electron acceptor used in efficient bulk heterojunction (BHJ) organic solar cells (OSCs). Herein, we report a structurally non-planar molecule TRIP-PDI3, in which a rigid and shape-persistent triptycene (TRIP) unit is employed as a central unit to collect three PDI arms at the periphery. As an electron acceptor, TRIP-PDI3 exhibits a low-lying LUMO energy level of -3.81 eV similar to that of conventional PCBM, but with an intensive light absorption in the range of 450-600 nm. BHJ OSCs were fabricated using TRIP-PDI as an electron acceptor and a low band gap polymer PBDT-TS1 as an electron donor, exhibiting a power conversion efficiency (PCE) of 4.53%. The result demonstrates that TRIP is a promising building block for the construction of structurally non-planar PDI derivatives as non-fullerene (NF) electron acceptors for efficient OSCs. |
