Abstract

A novel D-A conjugated polymer (PIBT-BDT) with 7-perfluorophenyl-6H-[1,2,5]thiadiazole[3,4-g]benzoimidazole is synthesized by the Stille coupling reaction. A memory device with PIBT-BDT as the active layer shows a large on/off ratio (>10⁵), good endurance (>100 cycles), and long retention (>10⁴ s). Through simulating the I-V curves and analysing energy barriers in the device structure, we suggest that the memory effect of Au/PIBT-BDT/ITO originates from the charge transfer between the strong acceptor (IBT) units and the donor BDT units.
