Strength in weakness: Nitrile and thiazolothiazole complexes as new materials for filamentary memristors

Memristors are passive electronic elements with two important features: memory (both nonvolatile and fading) and synapse-like plasticity. In most cases the devices are based on unconventional semiconducting materials, and hence they have unique electrical properties, including memory features. The current proposal is meant as a part of the quest for novel materials and elements with unique, memory-like features and improved performance with prospective application in neuromorphic computing. The main goal of the project is the development of a new strategy for fabrication of high performance, non-volatile memristors based on flexible materials. In order to this principal goal two intermediate goals must be achieved: (i) development of new materials capable of formation of conductive filaments on electrical stimulation and (ii) design and development of appropriate device structures for stable, forming-less memristive performance. In order to fulfil all these requirements the proposal will focus on several classes of silver and copper complexes. These metals offer rather high reduction potentials (additionally, copper offers CuII/CuI redox process, which may be also relevant from the point of view of resistive switching) and form complexes of moderate stability with different N-donating ligands.

Cyanothiazoles possess remarkable optical properties that can be fine-tuned through coordination with transition metals. In this study, we investigate a promising application of cyanothiazoles, where their combination with copper(I) iodide forms a new class of complexes exhibiting outstanding optical properties. X-ray crystallography of copper(I) iodide complexes with isomeric cyanothiazoles revealed key structural features, such...

In the present study, the structure, thermal stability, conductive properties, and antimicrobial activity of silver(I) complexes with nitrile ligands were investigated. For the construction of the materials, 2-cyanopyridine (2-cpy), 4-cyanopyridine (4-cpy), 1,2-dicyanobenzene (1,2-dcb), and 1,3-dicyanobenzene (1,3-dcb) were used in addition to the silver nitrite and nitrate. Four new compounds were isolated and structurally characterized:...
