Abstract:
1. An organic memory device comprising: a first electrode; an organic active layer on the first electrode, wherein the organic active layer includes an upper organic material layer formed of an electrically conductive organic material containing heteroatoms and a lower organic material layer formed of an electrically non-conductive organic material containing heteroatoms; and a second electrode formed on the organic active layer, wherein the organic active layer includes metal ions that are coordinated with the heteroatoms in the upper and lower organic material layers, wherein the electrically non-conductive organic material is selected from a group consisting of poly(4-vinylpyridine), poly(2-vinylpyridine), polystyrene-co-vinylpyridine, polystyrene sulfonic acid, polyacrylamide, poly(N-vinylimidazole) and mixtures thereof, and wherein the electrically conductive organic material includes a single molecule which includes a conductive moiety selected from a first group consisting of carbazole, triphenylamine, triphenyldiamine and mixtures thereof and which is bonded to a heteroatom-containing moiety selected from a group consisting of nitro, azo, indigo and thioindigo dyes and mixtures thereof.
