Abstract

A novel conjugated polymer, containing carbazole which acted as an electron-donor moiety, and a Pt(II) complex which acted as an electron-acceptor moiety, was synthesized and characterized. Electrical characterizations for the sandwiched polymer memory device (ITO/polymer/Al) indicate that the polymer possesses electrical bistability and the device exhibits resistive random-access memory. The memory mechanism has been investigated through theoretical calculations and attributed to the formation and dissociation of a charge-transfer state under the applied voltage. The device exhibits excellent memory performances, such as low threshold voltage, high ON/OFF current ratio, and good stability.
