Embodiment 1

[0027] A large number of organic-inorganic hybrid cuprous iodide anion high poly chain base semiconductor materials (MV) n (Cu 2 I 4 ) n The preparation of crystal sample: weigh 0.191g (1mmol) cuprous iodide and dissolve in 30 milliliters of acetonitrile to obtain clear solution A, weigh 0.222g (0.5mmol) methyl viologen iodide and dissolve in 5 milliliters of water to obtain clear Solution B; then, the above solution B was added to solution A, and it immediately became turbid. After the addition was completed, the stirring reaction was continued for half an hour, and a large amount of crystal products were formed. The crystals were filtered out, washed twice with water and ethanol, and dried in vacuum to obtain A large number of black crystals are the target product of the hybrid material, and the yield exceeds 80%.

Embodiment 2

[0029] Synthesis of Organic-Inorganic Hybrid Cuprous Iodide Anion Polymer Semiconductor Materials (MV) n (Cu 2 I 4 ) n single crystal: weigh 19mg (0.1mmol) of cuprous iodide and dissolve it in 5 milliliters of acetonitrile to obtain a clear solution A; weigh 22 mg (0.05 mmol) of methyl viologen iodide and dissolve it in 5 milliliters of water to obtain a clear solution B Then, solution B is first placed in the test tube, then solution A is slowly added to the test tube to make it on the upper layer of solution B, and the test tube is sealed and left to stand, after a few days, a large amount of black block crystals are separated out. Pick a black block crystal with a size of 0.18mm*0.12mm*0.10mm for X-ray single crystal structure test. The structure diagram of the crystallographic independent unit of this compound is shown in the attached figure 1 , the structure diagram of its cuprous iodide anion polymer chain and the corresponding counter cation methyl viologen is shown...
