A new soluble conjugated polymer, poly[{9-(4-methoxyphenyl)-9H-carbazole}(9,9-dioctylfluorene)(2,5-diphenyl-1,3,4-oxadiazole)](PCFO), was synthesized and was sucessfully used to fabricate a PCFO-based nonvolatile memory device. This device showed typical bistable electrical switching and nonvolatile write-once read-many-times memory performance, with a turn-on voltage of about −2.3 V and an ON/OFF state current ratio of ∼105.
