Abstract
Polymers are described which exhibit a resistive hysteresis effect. The polymers include a polymer backbone to which pentaarylcyclopentadienyl radicals are bonded as side groups. A resistive memory element is formed that includes the polymer as a storage medium. By applying a voltage, the memory element can be switched between a nonconductive and a conductive state.
