Embodiment 1
[0028] A large number of phosphorescent complex materials [Cu(2-iQBO)(POP)]PF 6 Preparation of microcrystalline sample: Weigh 0.054g of POP (0.1mmol), 0.024g of 2-iQBO (0.1mmol), 0.037g of Cu(CH 3 EN) 4 PF 6(0.1mmol); respectively add 3ml of dichloromethane to dissolve and mix, fully stir to make it fully take place coordination reaction, obtain deep red clear solution; add isopropanol in the above solution, and remove all solvents by rotary evaporation at room temperature , a red crystal product was finally obtained with a yield of 91% (calculated as Cu).
Embodiment 2
[0030] Synthesis of red phosphorescent complex material [Cu(2-iQBO)(POP)]PF 6 single crystal: Weigh 0.054g of POP (0.1mmol), 0.024g of 2-iQBO (0.1mmol), 0.037g of Cu(CH 3 EN) 4 PF 6 (0.1mmol); add 4ml of dichloromethane, stir fully to make it fully coordinate reaction, and obtain a deep red clear solution; after removing all solvents by rotary evaporation at room temperature, add 2ml of dichloromethane, and cover the solution with isopropyl Alcohol promotes the crystallization of the product, and after standing for a few days, a large number of dark red blocky crystals precipitate out. Pick a deep red block crystal with a size of 0.49mm*0.46mm*0.40mm for X-ray single crystal structure test. The molecular structure of the compound is shown in the attached figure 1 , and its unit cell packing structure is shown in the attached figure 2 .
[0031] For the red phosphorescent complex material [Cu(2-iQBO)(POP)]PF 6 A series of performance tests were carried out on pure phase...
