The electrical conduction mechanism of resistive switching Prussian white (PW) thin films obtained by the electrodeposition method was examined by AC impedance spectroscopy and DC current–voltage measurements. Using an electrode tip to contact PW grown over Au, robust unipolar resistive switching was observed with a current change of up to three orders of magnitude, high repeatability, and reproducibility. Moreover, electrical impedance spectroscopy showed that the resistive switching comes from small conductive filaments formed by potassium ions before the establishment of larger conductive channels. Both voltammetry and EIS measurements suggest that the electrical properties and conductive filament formation are influenced by defects and ions present in the grain boundaries. Thus, PW is a potential material for the next generation of ReRAM devices.

Polar-end 3,5-diarylisoxazol liquid crystals (ILCs) with nitro, amine and bromine polar terminal groups were thermally and structurally characterized. The nitro and bromo terminated compounds exhibited the highly ordered CrE mesophase below the conventional SmA. X-ray data obtained for the SmA mesophase showed that the structural organization of this phase evolves from monolayer SmA₁ (Br), to interdigitated SmA_d (NO₂), and to quasi-bilayer SmA₂ (NH₂). The optical band gap and photoluminescence quantum yields are strongly dependent on the terminal groups and complementary DFT calculations supported the experimental observations. Direct current (DC) electrical measurements demonstrated a significant dependence on temperature, exhibiting increased conductivity at elevated temperatures, regardless of the mesophase. Alternating current (AC) electrical measurements suggested the presence of ionic conduction, with a huge increase in capacitance at low frequencies.

We investigate a series of liquid‐crystalline phthalocyanines (metal‐free and Cu, Zn, Ni, Co complexes) and their electronic performance as active layers in organic thin‐film transistors (OTFTs). Raman spectroscopy reveals metal‐dependent distortions of the phthalocyanine macrocycles, reflected in systematic shifts of the C−N−C and M−N vibrational modes. When integrated into OTFTs, all compounds exhibited markedly enhanced current response under ultrahigh vacuum compared to an N ₂ ‐ atmosphere, demonstrating that intrinsic charge transport is suppressed by atmospheric species. Temperature‐dependent measurements (in the 100–300 K range) revealed that the threshold‐voltage shifts in the devices were driven by deep interface and bulk traps, while all devices displayed thermally activated mobility with low activation energies (≈14–20 meV). These results highlight how mesomorphic order, metal coordination, and environmental conditions collectively govern charge transport in liquid‐crystalline phthalocyanines, offering design guidelines for their use as self‐assembled semiconducting materials in organic electronics. Our results therefore represent a systematic characterization of liquid‐crystalline phthalocyanine‐based OTFTs, revealing low trap‐barrier energies and efficient charge‐hopping pathways present in these materials.
