Embodiment 1
[0030] Preparation of a large number of microcrystalline samples: weigh 0.3 mmol of cuprous iodide and dissolve it in 10 mL of acetonitrile to obtain solution A, weigh 0.3 mmol of p-anisyl 3 The P ligand was dissolved in 10 mL of dichloromethane to obtain solution B, and solution A and solution B were mixed, and stirred to make the coordination reaction fully occur, and finally the resulting colorless solution was filtered, and all solvents were removed by rotary evaporation, and vacuum-dried. The colorless crystalline powder was obtained as the product, and the yield was 97% (calculated as Cu).
Embodiment 2
[0032] Synthesis of Cu(I) Complex Cu 4 I 4 (p-anisyl 3 P) 4 single crystal: 0.1 mmol of cuprous iodide was dissolved in 4 mL of acetonitrile to obtain solution A, and 0.1 mmol of p-anisyl was weighed 3 The P ligand was dissolved in 6mL of dichloromethane to obtain solution B. Mix solution A and solution B, and stir to make it fully undergo a coordination reaction. Finally, filter the resulting colorless solution, and cover the filtrate with n-hexane to promote crystallization of the product. After standing for several days, a large number of colorless blocky crystals were precipitated. A colorless crystal with a size of 0.32mm×0.26mm×0.23mm was selected 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 .
[0033] For the complex Cu 4 I 4 (p-anisyl 3 P) 4 A series of performance tests were carried out on pure phase crystal samples....
