Electrical Properties of Cu-Based Coordination Complexes: Insights from In Situ Impedance Spectroscopy.

This study examines the influence of ligand design on the structural, optical, and electrical properties of copper-based coordination complexes. Ligands HL and HL were synthesized via the reaction of 5-nitrosalicylaldehyde with 2-hydroxy- or 4-hydroxybenzhydrazide. HL was obtained from the reaction of carbohydrazide and salicylaldehyde, while HL was prepared by condensing 4-methoxysalicylaldehyde with thiocarbohydrazide.

Green and Scalable Preparation of Highly Conductive Alkali Metal-dhta Coordination Polymers.

2,5-Dihydroxyterephthalic acid (H) is well-known for its use in the construction of functional metal-organic frameworks (MOFs). Among them, simple coordination polymers (CPs), such as lithium and sodium coordination polymers with H, have been used successfully to synthesize electrically conductive MOFs and have also demonstrated great potential as positive or negative electrode materials on their own. However, there has been little exploration of the structure and physicochemical properties of these and other alkali complexes of H.

The Crystallization Behavior of a NaO-GeO-PO Glass System: A (Micro)Structural, Electrical, and Dielectric Study.

Sodium-phosphate-based glass-ceramics (GCs) are promising materials for a wide range of applications, including solid-state sodium-ion batteries, microelectronic packaging substrates, and humidity sensors. This study investigated the impact of 24 h heat-treatments (HT) at varying temperatures on Na-Ge-P glass, with a focus on (micro)structural, electrical, and dielectric properties of prepared GCs. Various techniques such as powder X-ray diffraction (PXRD), infrared spectroscopy-attenuated total reflection (IR-ATR), and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) were employed.
