Synthesis and Electroluminescent Properties of Bis(3H-1,2,3-triazolo-[4,5-b]pyridine-3-ol)zinc Zn(TAP)2

[摘要] A new light-emissive material, bis(3H-1,2,3-triazolo-[4,5-b]pyridine-3-ol)zinc (Zn(TAP)2), has been synthesized and characterized by FT-NMR, FT-IR, UV-Vis, and elemental analysis. The photoluminescence (PL) of Zn(TAP)2was measured from the DMF solution at 460 nm. The HOMO (6.5 eV) and LUMO (2.8 eV) energy levels of Zn(TAP)2were estimated from the measurement of cyclic voltammetry. The devices with structures of ITO/NPB/Zn(TAP)2/LiF/Al and ITO/NPB/Zn(TAP)2/Alq3/LiF/Al were constructed to investigate their electroluminescent (EL) performance.Zn (TAP)2is supposed to be a good emitting material in the EL device.
