Abstract

A series of non-conjugated ferrocene-containing copolymers FcCP1-FcCP3 with a triphenylamine (TPA), benzothiazole (BT) or phenothiazine (PHZ) unit has been designed and synthesized via a facile radical polymerization protocol. The structural, photophysical, electrochemical and memory characteristics of these polymers were systematically studied. All the copolymers exhibited flash memory behaviour with a bistable conductive process, where FcCP1 showed a large ON/OFF current ratio of 10³ to 10⁴ with a low threshold voltage of -0.6 V. Such remarkable results suggest that non-conjugated ferrocene-containing copolymers are promising active materials for memory applications.
