specific Embodiment approach 3
[0030] Specific embodiment three: Specific embodiment one The preparation method of the blue organic luminescent material o-pyridine 2,6-substituted monoamine mercury complex is carried out according to the following steps:
[0031] 1. Under the condition of nitrogen protection, mix 20-30 mg of (2,6-dimethylphenyl)-pyridine-2-methyleneamine and 25-40 mg of HgCl 2 Dissolve in a mixed organic solvent, heat to reflux, and stir for 7 hours to obtain a yellow reaction liquid;
[0032] 2. Filter the product of step 1 while it is hot, and then volatilize at room temperature for 3 to 10 days to obtain [(2,6-dimethylphenyl)-pyridine-2-methyleneamine]HgCl 2 ;
[0033] The mixed organic solvent described in step 1 is CH 3 OH and CH 2 Cl 2 A mixed solution of which CH 3 OH and CH 2 Cl 2 The volume ratio is 1:5.
[0034] The reaction equation of the present embodiment is as follows
