Embodiment 1
[0027] Vast amount of semiconducting material (MV) n (Ag 2 I 4 ) n Crystal sample preparation: Weigh 0.136g (0.8mmol) of silver nitrate and dissolve it in 5ml of water, weigh 0.177g (0.4mmol) of methyl viologen iodide and 0.135g (0.8mmol) of potassium iodide and dissolve it in 10ml A clear solution A was obtained in water; then, the above silver nitrate solution was added to the solution A, and it immediately became turbid. After the addition was completed, it was heated while stirring, and a large amount of crystal products were formed after heating to boiling and kept for 15 minutes. At this time, the reaction was stopped, and the crystals were precipitated by filtration. , washed twice with water and ethanol respectively, and dried in vacuum to obtain a large amount of red crystals, which is the target product of the hybrid material, with a yield of more than 80%.
Embodiment 2
[0029] Synthetic Semiconductor Materials (MV) n (Ag 2 I 4 ) n Single crystal: Weigh 17mg (0.1mmol) of silver nitrate dissolved in 10ml of water to obtain a colorless clear solution A, weigh 22mg (0.05mmol) of methyl viologen iodide and 34mg (0.2mmol) of potassium iodide dissolved in Clear solution B was obtained in 10 ml of water; then, put solution B in the test tube first, then slowly add solution A into the test tube so that it was in the upper layer of solution B, seal the test tube and let it stand, a large number of red needles appeared after a few days Crystals precipitated. Pick a red needle-like crystal with a size of 0.51mm*0.08mm*0.04mm 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 silver iodide anion polyhelical chain and the corresponding counter cation methyl viologen is shown in the appendix figure 2 , and its unit ce...
Embodiment 3
[0031] Vast amount of semiconducting material (MV) n (Ag 2 I 4 ) n Crystal sample preparation: weigh 0.136g (0.8mmol) of silver nitrate and dissolve it in 5 milliliters of water, weigh 0.177g (0.4mmol) of methyl viologen iodide and 0.120g (0.8mmol) of sodium iodide and dissolve it in A clear solution A was obtained in 10 milliliters of water; then, the above-mentioned silver nitrate solution was added to the solution A, and it immediately became turbid. After the addition was completed, it was heated while stirring, and a large amount of crystal products were formed after heating to boiling and kept for 15 minutes. At this time, the reaction was stopped and filtered. The crystals are precipitated, washed twice with water and ethanol, and dried in vacuum. Finally, a large amount of red crystals are obtained, which is the target product of the hybrid material, and the yield exceeds 80%.
