Zinc Complex Based on 2-(5-Methyl-2-hydroxyphenyl)benzotriazole: Synthesis and Electroluminescence Characteristics

Abstract: Zinc (II) [2-(5-methyl-2-hydroxyphenyl)benzotriazole] (Zn(MHB)2) was synthesized and characterized by FT-NMR, FT-IR, UV-Vis, XPS and elemental analysis. The photoluminescence of Zn(MHB)2 was measured at 516 nm from the DMF solution. The HOMO (6.6 eV) and LUMO (3.1 eV) energy levels of Zn(MHB)2 were estimated from the measurement of cyclic voltammetry. The devices with structure of ITO/NPB/Zn(MHB)2/Alq3/LiF/Al were constructed to investigate their electroluminescent (EL) performance. Zn(MHB)2 was found to be a … Show more

“…The synthetic scheme of Zn(TAP) 2 is shown in Figure 1. The synthesis of Zn(TAP) 2 was followed the closely related literature procedure and our previous works [15][16][17][18]. First, a solution of zinc acetate dihydrate (0.211 g, 1 mmol) in methanol (5 mL) was gradually added to a DMF solution of 3H-1,2,3-triazolo-[4,5-b]pyridine-3-ol (TAP) (0.27 g, 2 mmol) and sodium hydroxide (0.08 g, 2 mmol) in 5 mL methanol.…”
