Embodiment 1
[0044] Synthesis of hole transport material POZ9 and its application in perovskite solar cells:
[0045]
[0046] (i) p-methoxybromobenzene (0.823g, 4.40mmol), phenothiazine (0.732g, 4.00mmol), catalyst palladium acetate (0.018g, 0.08mmol), tri-tert-butyl acetate (0.018g, 0.08mmol) were added to the dry reaction vessel Phosphorus (5% mmol), sodium tert-butoxide (0.577 g, 6.00 mmol) and solvent toluene (50 mL) were stirred uniformly at room temperature under nitrogen protection, and then heated to 110° C. to react for 24 h. After the reaction was completed, it was cooled to room temperature, 50 mL of dichloromethane was added to the reaction solution, and washed three times with 150 mL of water, the organic layer was collected, the solvent was removed under reduced pressure, and the residue was separated and purified by silica gel column chromatography, petroleum ether / dichloromethane Methane (4:1 vol / vol) was the eluent and dried in vacuo to give compound 1 (0.991 g, yield:...
