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 PF6 (0.1mmol); Mix after dissolving with 3ml of acetonitrile respectively, fully stir to make it fully take place coordination reaction, obtain deep red clear solution; Add a small amount of isopropanol and n-hexane in the above solution, and at room temperature rotary evaporation removes all solvent, and finally obtain a red crystal product with a yield of 93% (calculated as Cu).
Embodiment 2
[0030] Synthesis of orange-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 10ml of acetonitrile, stir fully to make it fully coordinate reaction, and obtain a dark red clear solution; after removing all solvents by rotary evaporation at room temperature, add 2ml of acetonitrile, and cover the solution with isopropanol to promote crystallization of the product , After standing for a few days, a large number of red blocky crystals were precipitated. Pick a red strip crystal with a size of 0.49mm*0.42.mm*0.38mm 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 orange-red phosphorescent complex material [Cu(2-iQBO)(POP)]PF 6 A series of performance tests were carried out on pure phase crystal ...
