عنوان انگلیسی Synthesis of a Novel 2-Methyl-8-Quinolinol Complex of Zn (II) and Its Use in Organic Light Emitting Diodes (OLEDs) Fabrication
چکیده انگلیسی مقاله A zinc complex, (Me-HQ-H) [ZnI₂(Me-HQ)], was synthesized via a straightforward reaction between ZnI₂ and 2-methyl-8-quinolinol (Me-HQ). The complex w:as char:acterized using multiple techniques, including elemental analysis (CHN),     FT-IR, ¹H and ¹³C NMR and UV–Vis spectroscopy, with its molecular structure confirmed through X-ray diffraction analysis. In the study of Organic Light Emitting Diodes (OLEDs), the zinc complex was employed as a dopant at two different concentrations to achieve green electroluminescence. Photoluminescence (PL), current-voltage (I-V), and electroluminescence (EL) evaluations were orchestrated, revealing that higher dopant levels led to charge trapping, which resulted in self-quenching and reduced efficiency. Green electroluminescence was observed at wavelengths of 517 nm and 539 nm from devices 2 and 3, respectively.
