Embodiment 1

[0027] A large number of organic-inorganic hybrid cuprous iodide anion polymer chain-based semiconductor materials (MV) n (Cu 2 I 4 ) n Preparation of crystal samples: Weigh 0.191g (1mmol) of cuprous iodide and dissolve it in 30ml of acetonitrile to obtain a clear solution A, weigh 0.222g (0.5mmol) of methyl viologen iodide and dissolve it in 5ml of water to obtain a clear solution solution B; then, the above solution B was added to the solution A to form turbidity immediately, and the stirring reaction was continued for half an hour after the addition was completed to form a large amount of crystal products, filtered to separate out the crystals, and then washed twice with water and ethanol, respectively, and vacuum-dried to finally 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 chain-based semiconductor material (MV) n (Cu 2 I 4 ) n Single crystal: Weigh 19 mg (0.1 mmol) of cuprous iodide and dissolve it in 5 ml of acetonitrile to obtain a clear solution A, weigh 22 mg (0.05 mmol) of methyl viologen iodide and dissolve it in 5 ml of water to obtain a clear solution B ; Then, put solution B in the test tube first, then slowly add solution A to the test tube to make it in the upper layer of solution B, seal the test tube and let it stand, after a few days, a large number of black block crystals are precipitated. A black bulk crystal with a size of 0.18mm*0.12mm*0.10mm was selected for X-ray single crystal structure testing. The structure diagram of the crystallographically independent unit of this compound is shown in the appendix figure 1 , the structure of its cuprous iodide anion polymer chain and the corresponding counter cation methyl viologen are shown in the appendix ...
