Embodiment 1
[0077] Measure titanium isopropoxide (0.16mL, 0.5mmol), pamoic acid (155mg, 0.4mmol), n-propanol (4.5mL) and dimethylformamide (1.5mL) into a 20mL glass bottle, at room temperature Mix evenly, add ethylenediamine (0.08mL, 0.04mmol) with a purity of 99% to the mixed reaction system, and then place it in a 100°C oven for constant temperature reaction for 3 days, take it out, cool it down to room temperature naturally, and separate the solid phase, and then wash the solid phase with n-propanol to obtain red octahedral Ti 4 L 6 crystalline product.
[0078] Change the titanium isopropoxide in the above scheme to zirconium n-propoxide or hafnium n-propoxide, use the same operation method and react under the same conditions, you can get yellow octahedral Zr 4 L 6 or Hf 4 L 6 crystalline product.
[0079] After testing, the Ti prepared in Example 1 4 L 6 、Zr 4 L 6 and Hf 4 L 6 The yields of crystalline products were all over 88%.
[0080] Ti prepared in embodiment 1 4 L...
Embodiment 2
[0086] Measure titanium tetrachloride (0.09ml, 0.4mmol), pamoic acid (120mg, 0.3mmol), n-propanol (4.5mL) and dimethylformamide (1.5mL) into a 20mL glass bottle, at room temperature Mix evenly, add ethylenediamine (0.08mL, 0.04mmol) with a purity of 99% to the mixed reaction system, then place it in an oven at 100°C for 3 days, take it out, let it cool down to room temperature, and separate the solid phase. Rinse with n-propanol to get red dodecahedron Ti 4 L 6 crystalline product.
[0087] Change the titanium tetrachloride in the above scheme to zirconium tetrachloride or hafnium tetrachloride, use the same operation method and react under the same conditions, you can get the yellow dodecahedral Zr 4 L 6 or Hf 4 L 6 crystalline product.
[0088] After testing, the Ti prepared in Example 2 4 L 6 、Zr 4 L 6 and Hf 4 L 6 The yield of crystalline product exceeds 86%.
[0089] Ti prepared in embodiment 2 4 L 6 、Zr 4 L 6 and Hf 4 L 6 It is an isomorphic compound, ...
