Novel ternary memory property achieved through rational introducing of end-capping naphthalimide acceptors

Abstract

Small molecule based multilevel rewritable memory device gained increasing attentions recently since its abilities to possess super-high storage density, to sustain the stored data without power supply and to erase and rewrite electrically. However, small molecule-based multilevel flash-type memory is extremely challenging. Herein, we designed a symmetric molecule with end-capping naphthalimide acceptors through rational tuning. This molecule showed an improved crystal size and uniform crystal orientation in film state. The sandwich-structured device exhibited the typical WORM memory property from OFF to ON1 transition and encouraging flash memory behavior for the ON1/ON2 transition. It is the first report about small molecule based ternary memory device with rewritable memory behavior, and this work will inspire the exploration of multilevel data-storage devices with fully rewritable properties in the following researches.
