New luminescent zinc complexes were obtained by reaction of pyrazolone-based azomethine ligands with Zn(CH3COO)2·2H2O. Complexes fully characterized by elemental analysis, FTIR, ES–MS, NMR, and single crystal X-ray analysis. Title complexes in the solid state demonstrate tunable luminescence from blue to orange by varying of substituents on the aromatic ring. Quantum yields are in the 0.03 to 0.49 range. TGA data shows that obtained complexes demonstrate high thermal stability and can be used as electroluminescent materials. The electrical properties of the complexes under study were considered in the ITO-Zncomplex-Al “sandwich” structure.
The 4-methylphenylhydrazone N-isoamylisatin method consists of 4-methylphenylhydrazone and a diode heterostructure. The best method for producing, synthesizing, microscopy of carbon films and an organic precursor. The results of the successive x-ray phase analysis of the materials used are presented. Also, the optical spectra of isatins having short wavelength (420-500 nm) and long wavelength (850-900 nm) extrema giving absorption peaks at 3-3.1 eV and luminescence at 1.4 eV. The results of studies of IR spectroscopy of primary carbon films and an organic composite are obtained. The current-voltage characteristics of a thin-film heterostructure based on a fullerene-accessible material and an organic precursor with ITO-aluminum strapping are presented. It was shown that the experimental structures have rectifying diode characteristics with hysteresis of the forward branch of the I-V characteristic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
