Abstract

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)2 was measured from the DMF solution at 460 nm. The HOMO (6.5 eV) and LUMO (2.8 eV) energy levels of Zn(TAP)2 were 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)2 is supposed to be a good emitting material in the EL device.
