A research group of the Department of Chemistry, College of Science have published an article about selenazone ligand nanoparticles analogues of dithizone at the Indonisian Journal of Chemistry.

In this research articleو A new method for preparing 1,5-diphenylselenocarbazone (selenazone) nanoparticles and their complexes with Pb²⁺, Cd²⁺, Co^2+, and Ni²⁺ has been performed using hot methanol solvent. The ligand and its complexes were characterized using FT-IR, UV-Vis, ¹H-NMR, ¹³C-NMR, X-ray powder diffraction (XRD), EI-mass spectrometry, scanning electron microscopy (SEM), HG and flame-atomic absorption spectrophotometer, thermal analysis (TG/DTA), and molar conductance measurements. The molar conductance measurements in all complexes were recorded low values in DMSO, indicating that all the metal complexes were non-electrolytes except the nickel complex that possessed an electrolytic nature. Kinetic and thermodynamic parameters of complexes (A, E, ∆H, ∆S, and ∆G) have been computed using three kinetic models of Coast-Redfern, Broido, and Horowitz-Metzger, that illustrated the decomposition reactions in all steps were nonspontaneous. Thermogravimetric analyses (TG/DTA) were consistent with the atomic spectroscopy data proving that the geometry shape of all the complexes was octahedral.
