Abstract
The invention relates to an organic electroluminescent material Zn (n-RBTZ) 2 based on benzothiazolyl, which has the structure general formula shown in formula (I) and is prepared by leading ligand material which is the product obtained by the reaction between salicylic acid ramification and ortho-amino thiophenol to react with zinc acetate. The Zn (n-RBTZ) 2 prepared by the invention has higher thermal stability, and fluorescence quantum efficiency of the Zn (n-RBTZ) 2 is higher than that of Zn (BTZ) 2, so that the electron transport performance of the material is improved, the phenomenon of unbalanced carrier transport in a cavity layer and a luminous layer in an organic electroluminescent device is overcome, and the stability of the device is improved. The Zn (n-RBTZ) 2 is blue light emitting material with good performance, which has broad band luminescent spectrum and can be expected to be compounded with other colors such as red to realize white light emission. In the formula, R represents C1-C3 alkyl, C1-C3 alkoxy, or C1-C3 alkyl or halogen atom substituted by one or more halogen atom (s).
