“…However, the nature of complexation has again been confirmed by performing the solution state conductivity experiment with the polymer. The conductivities of varying concentrations of the solution of Ru(II)-poly have been observed (see Table S2) and found to remain almost unaffected by different concentrations of the polymer solution, [44] thereby confirming the presence of a neutral Ru(II) complex.…”

Metallo‐supramolecular polymers offer ample opportunity to develop new emergent materials with the potential for applications as future memories. In this context, we have synthesized a novel hybrid polymer of our developed Schiff base ligand with Ru(II)‐metal ion. The main objective of this study is to understand the effect of changing central metal ion on the ligand field stabilization energy, and the band gap of material as the biting angle of organic moiety changes accordingly with a change in cationic radius of the central metal ion. Furthermore, we have also investigated the application in non‐volatile memory devices. Complete characterization of the newly synthesized hybrid polymer has been performed to establish its structure as well as oxidation state of the central metal ion. A comparative study of the present case and the previously reported Fe(II)‐polymer provides a clear insight into the effect of incorporating a bigger size metal ion in the polymer chain. Non‐volatile memory properties of the polymer have shown a rare behaviour of Negative Differential Resistance (NDR) along with the Low Resistive State (LRS) as its pristine state. Remarkable charge retention and endurance test have also been demonstrated.

“…The huge possibilities of tailorability of metallopolymers make them susceptible to work as stimuli‐responsive materials, which are classified as photo‐, chemo‐, electro‐, mechano‐, according to the kind of stimuli applied 27,28 . This opens up the applicability of the metallopolymers in the different advanced fields such as electrochromic, 29 photoluminescent, 30,31 chemosensing or chemoluminescent, vapoluminescent, electroluminescent, 13,32 and memristive switching 12,16,18,21 as an emerging new substituent. The field of memristive materials is revolutionizing daily with different metallopolymers to overcome the requirement of fast data processing, low power consumption, and miniaturization of the device size, which has triggered the storing of a huge amount of information in a small area 12,16,18,21 .…”

In this study, Al(III)-metallopolymer is synthesized with our previously reported ligand to understand the difference in the interaction of the reported ligand with transition metal ions (Fe(II) and Cr(II) ions) and smaller cationic radius main group metal ion. Al(III)-metallopolymer is thoroughly characterized by different analytical techniques to understand the structure-property relationship. Surface morphological analyses reveal the formation of long nano-fiber strands on the respective substrates. This polymer has shown reversible redox behavior, which is ligand centric as no d-orbitals are available on the central metal ion for the electron push-pull mechanism. Al(III)metallopolymer is fluorescent active, and it is shown a reversible change in absorption spectrum on the application of the appropriate potential. This ligand-based redox-switching also generates a bistable state when a metalinsulator(thin film of polymer)-metal sandwich device is probed in between ±1 V, and it is stable in the ambient condition to sustain several flip-flop cycles without any degradation for 10 3 s as observed from the experimental data. This work enlightens a new metallopolymer with a low value of SET-RESET voltage and a long retention time for the future memristive device, which can operate at very low voltage compared to conventional Si-based memory chips.
