“…The formation of unique nanoparticles with strong noncovalent intermolecular interactions-supermolecules from magnesium porphine, a functional element of chlorophyll, has been reported [43]. Interactions between corrin macrocycles of hydrophobic corrinoids are observed upon the formation of supermolecular nanoentities with distinct optical and redox properties that are stable even in solutions [50,52]. Besides π-electron system of corrin ring, another important feature of cobalamins affecting their redox behavior is the presence of cobalt ion, which can adopt 3+, 2+, and 1+ oxidation states [53].…”

Memristive devices offer essential properties to become a part of the next-generation computing systems based on neuromorphic principles. Organic memristive devices exhibit a unique set of properties which makes them an indispensable choice for specific applications, such as interfacing with biological systems. While the switching rate of organic devices can be easily adjusted over a wide range through various methods, controlling the switching potential is often more challenging, as this parameter is intricately tied to the materials used. Given the limited options in the selection conductive polymers and the complexity of polymer chemical engineering, the most straightforward and accessible approach to modulate switching potentials is by introducing specific molecules into the electrolyte solution. In our study, we show polyaniline-based device switching potential control by adding nucleotide-free analogue of vitamin B12, aquacyanocobinamide, to the electrolyte solution. The employed concentrations of this molecule, ranging from 0.2 to 2 mM, enabled organic memristive devices to achieve switching potential decrease for up to 100 mV, thus providing a way to control device properties. This effect is attributed to strong aromatic interactions between polyaniline phenyl groups and corrin macrocycle of the aquacyanocobinamide molecule, which was supported by ultraviolet-visible spectra analysis.
