The team from the Department of Chemistry, comprising Edi Topić, Mirta Rubčić, Jana Pisk, and the recently graduated Josip Sarjanović, in collaboration with scientists Lidija Androš Dubraja and Luka Pavić from the Ruđer Bošković Institute, have published a significant research article titled Evaluation of vanadium conversions derived from simple acetic acid hydrazide as non-conventional semiconductors in the Journal of Materials Chemistry C, Materials with applications in optical, magnetic & electronic devices (IF=6.4)
This study delves into the electrical characteristics of vanadium complexes obtained from acyl-hydrazone ligands. Impedance spectroscopy, a technique that spans a broad spectrum of frequencies and temperatures, aimed to to elucidate the relationship between temperature-induced structural transformations and the electrical conductivity of the materials under investigation. The analysis is further supported by temperature-dependent X-ray powder diffraction and thermogravimetric data, enhancing the precision of the measurement optimisation process.
Given the scant representation of vanadium coordination compounds as semiconductors in existing literature, this research offers novel insights that promise to deepen the scientific community's comprehension of this class of materiala. Additionally, the study explores the optical characteristics of vanadium-based materials, identifying impedance spectroscopy as a valuable method for real-time observation of the coordination complexes' transitions. The findings suggest that these materials possess considerable potential for application as semiconductors in a variety of electronic devices.
This research was conducted as a part of the Cogito project, titled "Sustainable Polyesters with Mo and V Catalysts," project number 49260RA.
