Embodiment 1

[0027] A large number of organic-inorganic hybrid bismuth iodide anion cluster-based semiconductor materials (MV) 2 (Bi 4 I 16 ) Crystal sample preparation: weigh 0.603g (1mmol) of bismuth iodide and dissolve it in 40 milliliters of acetone to obtain a clear solution A, weigh 0.222g (0.5mmol) of methyl viologen iodide and dissolve it in 8 milliliters of water to obtain a clear solution 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 dark red crystals are the target product of the hybrid material, and the yield exceeds 80%.

Embodiment 2

[0029] Synthesis of organic-inorganic hybrid bismuth iodide anion cluster-based semiconductor materials (MV) 2 (Bi 4 I 16 ) single crystal: weigh 60mg (0.1mmol) of bismuth iodide and dissolve it in 5 milliliters of acetone 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 deep red block crystals are precipitated. Pick a deep red block crystal with a size of 0.18mm*0.16mm*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 structures of its bismuth iodide anion cluster and the corresponding counter cation methyl viologen are shown in the ...
