AbstractInteractions between metal ions and ligands in metal-containing polymers involve two bonding extremes: persistent covalent bonding, where the polymers are essentially static in nature, or labile coordination bonding, which leads to dynamic supramolecular materials.Main chain polymetallocenes based on ferrocene and cobaltocene fall into the former category due to the presence of strong metal-cyclopentadienyl bonds. Herein we describe a main chain polynickelocene formed by ring-opening polymerization of a moderately strained[3]nickelocenophane monomer, that can be switched between static and dynamic states as a result of the relatively weak Ni-cyclopentadienyl ligand interactions. This is illustrated by the observation that, at low concentration or at elevated temperature in a coordinating or polar solvent, depolymerization of the polynickelocene occurs. A study of this dynamic polymermonomer equilibrium by 1 H NMR spectroscopy allowed for determination of the associated thermodynamic parameters. Microrheology data, however, indicated that under similar conditions the polynickelocene is considered to be static on the shorter, rheological timescale.2

“…68 The memory cell can store in formation electrochemically recorded in the form of (i) a possible redox state of the complex or (ii) a number of the redox states taken in a preset ratio (this is specified by the voltage applied) over a period of 600 h. Ferrocene containing polymer 14 acquires conducting properties upon electrochemical oxidation to corresponding ferri cinium cation and can retain them for 7 h at room tem perature. 69 Recently, considerable advances in fabrication of non volatile redox based molecular memory systems have been made by researchers from a multidisciplinary group at the Califormia NanoSystems Institute. They reported a molecular memory array with a data density of 100 Gbit cm -2 .…”

We have reported about bipolar resistive switching effect on Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]:Graphene oxide composite films, which are sandwiched between aluminum and indium tin oxide electrodes. In this case, I-V sweep curve showed a hysteretic behavior, which varied according to the polarity of the applied voltage bias. The device exhibited excellent switching characteristics, with the ON/OFF ratio being approximately two orders in magnitude. The device had good endurance (10 5 cycles without degradation) and long retention time (5 × 10 3 s) at room temperature. The bistable switching behavior varied according to the trapping and de-trapping of charges on GO sites; the carrier transport was described using the space-charge-limited current (SCLC) model.
