Embodiment 1
[0028] A large number of phosphorescent complex materials [Cu(2-QBI)(m-Tol 3 P) 2 ]PF 6 Crystal sample preparation: weigh 0.037g (0.1mmol) of Cu(CH 3 EN) 4 PF 6 , 0.061 g (0.2 mmol) of m-Tol 3 P, 0.024g (0.1mmol) of 2-QBI; after dissolving with 5ml of dichloromethane respectively, mix successively, fully stir to make it fully take place coordination reaction, obtain orange-red clear solution; Add a small amount of n-hexane in the above solution, All the solvent was removed by rotary evaporation at room temperature to finally obtain a yellow crystal product with a yield of 92% (calculated as Cu).
Embodiment 2
[0030] Synthesis of yellow phosphorescent complex material [Cu(2-QBI)(m-Tol 3 P) 2 ]PF 6 single crystal: Weigh 0.037g (0.1mmol) of Cu(CH 3 EN) 4 PF 6 , 0.061 g (0.2 mmol) of m-Tol 3 P, 0.024g (0.1mmol) of 2-QBI; respectively dissolved in 5ml of dichloromethane and mixed successively, fully stirred to make it fully undergo a coordination reaction to obtain an orange-red clear solution; after filtering, cover the upper layer of the solution with n-hexane The crystallization of the product was promoted, and a large number of yellow blocky crystals were precipitated after standing for a few days. Pick a yellow block crystal with a size of 0.23mm*0.16mm*0.15mm 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 yellow phosphorescent complex material [Cu(2-QBI)(m-Tol 3 P) 2 ]PF 6 A series of performance tests were carr...
