Patent ID: 8003221

Claim:
An organic memory device comprising a first electrode, a second electrode and an organic active layer between the first and second electrodes, wherein the organic active layer is formed of a metallocenyl dendrimer represented by Formula 1: wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , which is identical to or different from each other, are independently H, a C 1 -C 20 alkyl group, a C 1 -C 20 alkoxy group, a C 3 -C 20 cycloalkyl group, a C 3 -C 20 heterocycloalkyl group, a C 5 -C 30 aryl group, a C 5 -C 30 heteroaryl group, a C 7 -C 30 arylalkyl group, or a C 5 -C 30 aryloxy group: Z 1 , Z 2 and Z 3 , which is identical to or different from each other, are independently a single bond, —C═C—, —(CH 2 ) n in which n is from about 1 to about 20 or a carbonyl group; and M is Fe, Ru, Zr or Ti.
