[0031] Example 1
[0032] 5,5',5"-(4,4',4"-nitrilotribenzamide)triisophthalic acid (17 mg, 0.02 mmol), Zn(NO 3 ) 2 ·6H 2 O (29.7 mg, 0.1 mmol) was dissolved in N,N'-diethylformamide (2 mL) and ethanol (1 mL) and stirred well. The solution was placed in an oven, fired at 100°C for 72 h, and the oven was turned off. After cooling to room temperature, colorless to pale yellow cubic crystals were formed, filtered and dried to obtain the target material Zn-L with a yield of about 60%. Elemental Analysis (%) for Zn 7 C 90 N 8 O 62.50 H 111 : C45.95, H 3.63, N 5.36%. Found: C 46.30, H3.70, N 5.19%. The obtained target material structure is as follows figure 1 The XRD pattern of the target material is shown in image 3 As shown, the thermal analysis diagram is shown in Figure 5 shown.

[0035] Example 3
[0036] 5,5',5"-(4,4',4"-nitrilotribenzamide)triisophthalic acid (17 mg, 0.02 mmol), Cu(NO 3 ) 2 ·3H 2 O (24 mg, 0.1 mmol) was dissolved in N,N'-dimethylformamide (2 mL) and concentrated HNO 3 After stirring evenly in (300 μL), the solution was placed in an oven, fired at 60°C for 72 h, the oven was turned off, cooled to room temperature, green octahedral bulk crystals were formed, filtered and dried to obtain the target material Cu-L, The yield is about 70%. Elemental Analysis (%) for Cu 6 C 90 N 8 O 42.75 H 73.50 : C46.36, H 4.11, N 6.69%. Found: C 47.24, H4.13, N 6.64%. The obtained target material structure is as follows figure 2 The XRD pattern of the target material is shown in Figure 4 As shown, the thermal analysis diagram is shown in Image 6 The adsorption curves of nitrogen and carbon dioxide are shown in Figure 7 shown.
