First Time

This study reports the fabrication and characterization of polymer resistive switching memory devices fabricated from poly(ether sulfone)s (PESs), containing carboxylic functional groups for hydrogen bonding with disperse red 1. PES-based supramolecular memory devices exhibited write-once read-many-times-type memory effects, with low switching threshold voltages below −5.0 V and high ON/OFF current ratios of 105. It is the first time that the concept of azobenzene supramolecular PES based on hydrogen bonding for electrical memory device application was investigated. A possible switching mechanism based on the charge transfer interaction was proposed through molecular simulation, optical absorption, and cyclic voltammetry. These results render the PES-based supramolecular memory devices as promising components for high-performance polymer memory devices.
