[0033] Step 1: First, weigh 0.05 g Cs 2 CO 3 Put it into a three-necked flask, add 4 ml 1-octadecene, and add 0.35 mL oleic acid, then place it in an oven and dry it at 80°C for 0.5 h to remove excess water, then pump nitrogen at room temperature to further remove excess Oxygen and moisture, heated to 140 ℃, until Cs 2 CO 3 Dissolve completely, cool down to 110°C to obtain the first mixed solution, and set aside;
[0034] Step 2: First, weigh 0.02g SnCl 2 Add it into a three-necked flask, then add 3.5 mL of 1-octadecene into the three-necked flask, place it in an oven and dry it at 80°C for 0.5 h, remove excess moisture, pump nitrogen at room temperature to remove excess air and moisture, and then raise the temperature to 110°C ℃, after 0.5h the SnCl 2 Completely dissolve to obtain the second mixed solution;
[0035] Step 3: After raising the temperature of the second mixed solution to 140°C, inject 0.25 mL of oleic acid and 0.35 mL of oleylamine into the system, and the...
