[0048] Synthesis of photoelectric functional material CzPFO and its application in perovskite solar cells
[0049] 1) Weigh the drug, put 2,2'-dibromobiphenyl (1.25 g) into a 50 mL double-necked round-bottom flask, add a stirring magnet, and use a double-row tube to evacuate and repeatedly blow in argon gas 3 times, Finally fill the balloon. Set up the apparatus so that it is under argon protection. Cool the flask in an ice bath for 10 min, turn on the magnetic stirrer, and slowly add 25 mL of newly distilled tetrahydrofuran (THF) solvent dropwise with a syringe, inject it into the reactor, shake it well, and the drug is fully dissolved. Add dry ice around the bottom of the double-necked round-bottom flask to keep the reaction system at -78 °C, slowly drop 6.25 mL of n-butyllithium reagent into the above-mentioned vacuum-tight flask, react for 1 h, and change from transparent to milky white. Use a syringe to quickly inject 2.0 mL of phosphorus chloride into a 50 mL single-ne...

Add dry ice around the bottom of the double-necked round-bottom flask to keep the reaction system at -78°C, slowly drop 6.25 mL of n-butyllithium reagent into the above-mentioned vacuum-sealed flask, react for 1 h, and change from transparent to milky white. Use a syringe to quickly inject 2.0 mL of phosphorus chloride into a 50 mL single-necked bottle that has been evacuated and fille...
