Patent ID: 8008653

Claim:
An organic active layer comprising: a mixture of a conductive polymer and a metallocene compound of Formula 1 below: CpMCp′ (1) wherein Cp and Cp′ are each independently one of cyclopentadienyl and indenyl which is one of unsubstituted and substituted with at least one substituent selected from R and OR, in which each R, which is one of identical and different, is one of C 1-20 alkyl, C 3-20 cycloalkyl, C 5-30 heterocycloalkyl, C 2-20 alkenyl, C 6-20 aryl, C 5-30 heteroaryl, C 7-20 arylalkyl and C 7-30 heteroarylalkyl, M is Zr, and the organic active layer is a bistable element configured to switch between a high resistance state and a low resistance state based on an applied voltage.
