An all-organic electrically bistable device and its application in non-volatile memory is reported (see Figure). The switching mechanism is attributed to electric-field-induced charge transfer from an organic electron donor to an acceptor, so that the device switches from a low- to a high-conductivity state. This device provides a new direction for data-storage technology based on organic composites.
