Conductivity Switching and Electronic Memory Effect in Polymers with Pendant …

ABSTRACT Electronic memory devices having the indium-tin oxide/polymer/Al sandwich structure were fabricated from polymers containing pendant azobenzene chromophores in donor-acceptor structures. The reversibility, or rewritability, of the high-conductivity (ON) state was found to be dependant on the terminal moiety of the azobenzene chromophore. While the polymers with electronaccepting term…
