A Donor-Acceptor structured conjugated copolymer PCNCzF was designed and synthesized for flexible polymer memory. The fabricated Al/PCNCzF/ITO-coated PET device exhibited non-volatile WORM memory effect, with the switch-on threshold voltage of - 1.4 V, and an ON/OFF current ratio of more than 10(4). The reliability and mechanical stability of the flexible memory device was deduced from the endurance and bending tests. Theoretical simulation, in-situ fluorescence spectra, as well as C-AFM measurements were employed to evaluate the switching mechanism of the memory device. The present flexible memory device was expected to meet the demand for flexible electronics applications. (C) 2017 Elsevier B.V. All rights reserved.
