英文摘要	A series of soluble aromatic polyimides were prepared from 2,2'-diphenyl-4,4'-biphenyl diamine (DPBD), 2,2'-bis(biphenyl)-4,4'-biphenyl diamine (BBPBD), 2,2'-bis[4-(naphthalen-1-yl)phenyl]-4,4'-biphenyl diamine (BNPBD) and 2,2'-bis(3,5-dimethoxyphenyl)-4,4'-biphenyl diamine (BMPBD) by polycondensation with 2,2'-bis[4'-(3 '',4 '',5 ''-trifluorophenyl)phenyl]-4,4',5,5'-biphenyl tetracarboxylic dianhydride via a two-step procedure. The resulting polymers were fully characterized and they exhibited excellent organosolubility, high thermal and dimensional stability. Resistive switching devices with the configuration of Al/polymer/ITO were constructed from these polyimides by using conventional solution coating process. Devices with the active layer based on DPBD, BBPBD and BNPBD exhibited nonvolatile and rewritable flash type memory characteristics with the turn-on voltage at -2.0 to -3.0 V and the turn-off voltage at 2.0-3.0 V. Whereas, device based on BMPBD demonstrated a bipolar write-once read-many times (WORM) memory capability with the writing voltage around +/- 3.0 V. The ON/OFF current ratio of these devices was of about 10(6) and the retention times can be as long as 10(4) s. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
