Abstract© 2018 The Royal Society of Chemistry. A novel propeller-shaped molecule (HPB-PDI6) with a hexaphenylbenzene (HPB) core and six peripheral PDI units was synthesized via Co2(CO)8-catalyzed cyclotrimerization and used as an acceptor for organic solar cells (OSCs). The intriguing geometry of the HPB core and the spatial repulsion of the PDI rings created a twisted three-dimensional propeller-shaped conformation for HPB-PDI6. The propeller-shaped conformation could prevent the acceptor molecules from forming large aggregates in the active layer. As expected, the PTB7-Th:HPB-PDI6 blend films show a favorable morphology as well as high and balanced charge carrier mobility. Devices based on PTB7-Th:HPB-PDI6 achieved a PCE of 6.63% with a Voc of 0.92 V, a Jsc of 15.11 mA cm-2, and an FF of 48.0%. Our results have demonstrated that the easily prepared propeller-shaped HPB-PDI6 could be a promising acceptor for high efficiency organic solar cells.
