Organic light-emitting diodes (OLEDs) are believed to be the next-generation flat panel displays due to low driving voltage, high contrast, ease of fabrication, wide viewing angle and low cost. In this field, the development of novel luminescent organic/organometallic compounds is key to enhance the performance of organic and polymeric light-emitting devices. Since the first OLEDs with Zn complexes were reported in 1993, synthesis of novel zinc complexes as active materials for OLEDs have focused on improving electron mobility or producing a blue shift or red shift emission compared to Znq2. In this work, we synthesized a hybrid zinc complex of 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (TP) and 8-hydroxyquinoline (H) ligands, Zn (TPH). The structure of Zn (TPH) was determined by 1H-NMR, 13C-NMR, FT-IR, UV-Vis, XPS and elemental analysis. Zn (TPH) shows a yellow emission under excitation by UV lamp of 365 nm. The photoluminescence and electroluminescence (EL) properties will be discussed.
