Using PCl3 as dehydrating agent, 2 (2-hydroxyphenyl) benzothiazole was synthesized by dehydration of o-aminothiophenol and salicylic acid, and the resulting product was further reacted with zinc acetate to synthesize 2 And thiazole chelate zinc (Zn (BTZ) 2) material. The complex was used as a luminescent layer to prepare ITO PVK: TPD Zn (BTZ) 2 Al near-white electroluminescent device with the color coordinates in the white field (x = 0.242, y = 0.35 9). When the driving voltage is 1 6V, the brightness reaches 32 0 cd m2, and the corresponding quantum efficiency is 0.32%. Furthermore, Zn (BTZ) 2 was doped with Ru Brene as an orange-red dye to make ITO PVK: TPD Zn (BTZ) 2: Rubrene Al structure. y = 0.343), very close to the white isosponential point, and the quantum efficiency of 0.474%. Finally, the luminescence and electrical properties of the above devices were deeply studied and discussed
