Resistive memory devices based on a triphenylamine-decorated non-precious cobalt(II) bis-terpyridine complex

The ITO/active material/Au sandwiched devices of a cobalt(II) bis-terpyridine complex decorated with two triphenylamine motifs display appealing flash-type resistive switching with a large ON/OFF ratio ( 4103) and low operating voltages (< +/- 3 V). In contrast, devices with the triphenylamine-appended terpyridine ligand show WORM-type memory behaviour.
