Neuromorphic computation has emerged as a potential alternative to subvert the von Neumann bottleneck issue in conventional computing. In this context, the development of resistive switching-based memristor devices mimicking various synaptic functionalities has engendered paramount attention. Here, we report a triradical-containing trinuclear Pd(II) cluster with a cyclohexane-like framework constituted by the Pd-Se coordination motif displaying facile memristor property with neuromorphic functionality as a thin-film device.

A thorough investigation is essential for unveiling the actual mechanism. In this study, we provide compelling evidence of the NDR effect with a remarkably high peak-to-valley current ratio and proton-diffused superionic conductivity in quantum-confined water molecules anchored to a thin film of 2D TMDs.

Controlled ligand-centered oxidation of afforded two mononuclear complexes, [Co(L)(L)] ([]) and [Co(L)] ([]), which upon further ligand-centered reduction yielded a di-azo-anion diradical complex, [Co(L)] (). In complex , two three-electron reduced di-azo-anion monoradical ligands () bridge two intermediate Co(III) centers at a distance of 2.

Advantageous polar solvent compatibility of 2D MoSfrom this method were utilized to fabricate thin film devices very easily and cost-effectively using polystyrene as matrix. Prominent RS property of polystyrene thin film devices with varying MoSconcentrations strongly favors electroforming-free operation.
