Embodiment 1
[0025] Example 1 Preparation of organometallic complex crystals of platinum
[0026] 1) Add 10g of 2,2'-bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole into 100ml of ethanol, then add glycine and stir to dissolve;
[0027] 2) Add acetic acid aqueous solution to the solution in step 1) to adjust the pH to 3.2, and then raise the temperature to 40-45°C;
[0028] 3) Add 1 mol / L aqueous solution of platinum acetylacetonate to the solution in step 2). After the addition, raise the temperature to 60-65°C and stir for more than 12 hours; calculated by molar ratio, 2,2'-bis(o-chlorophenyl) -4,4',5,5'-tetraphenyl-1,2'-biimidazole: glycine: acetylacetonate metal salt=4: 2.3:2.2;
[0029] 4) Cool down to room temperature, adjust the pH to 8.2 with sodium bicarbonate to obtain an alkaline solution;
[0030] 5) The alkaline solution was left to stand for more than 32 hours to form a large amount of solids, filtered, the filter cake was rinsed with n-heptane, and then dried und...

[0032] Example 2 Preparation of Zinc Organometallic Complex Crystals
[0033] 1) Add 10g of 2,2'-bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole into 100ml tetrahydrofuran, then add glycine and stir to dissolve;
[0034] 2) Add aqueous oxalic acid solution to the solution in step 1) to adjust the pH to 3.2, and then raise the temperature to 40-45°C;
[0035] 3) Add 1 mol / L aqueous solution of platinum acetylacetonate to the solution in step 2). After the addition, raise the temperature to 60-65°C and stir for more than 12 hours; calculated by molar ratio, 2,2'-bis(o-chlorophenyl) -4,4',5,5'-tetraphenyl-1,2'-biimidazole:glycine:acetylacetonate metal salt=4: 2.3:2.5;
[0036] 4) Cool down to room temperature, adjust the pH to 8.2 with sodium bicarbonate to obtain an alkaline solution;
[0037] 5) The alkaline solution was left to stand for more than 32 hours to form a large amount of solids, filtered, the filter cake was rinsed with n-heptane, and then dried under r...
