Abstract: Polymer memory devices based on a π -conjugated poly [9,9-bis(4-diphenylaminophenyl)-2,7-fluorene] covalently bridged, Disperse Red 1 (a dye) triad were fabricated. The devices exhibit electrical bistability in the I-V characteristics and can be used to perform read-write-erase memory functions. The memory devices exhibit good performance with an on/off current ratio up to 103 and stable on and off states under a constant voltage stress and read pulses. Furthermore, memory retention tests show that it is possible to preserve both states at 150 °C under ambient atmosphere for about 1 h when using Cu as the top electrode. © 2008 American Institute of Physics.
