Embodiment 1
[0030] Preparation of a novel metal-organic framework material 9,10-bis(ethynylpyridine)anthracene-1,4-terephthalate zinc: Take 0.009mmol Zn(NO 3 ) 2 ·6H 2 O, 0.009 mmol H 2 bdc, 0.018 mmol 9,10-bis(ethynylpyridine)anthracene, was added to a 4-dram vial, and 1.6×10 -2 mol N,N'-dimethylformamide (DMF), and then put the bottle into an oven at 85°C to react for 48 hours to obtain a crude porous zinc metal-organic framework; wash the crude porous zinc metal-organic framework with ethanol Dry at 80°C to obtain red partial cubic layered crystals—purified porous zinc metal-organic framework materials, with a yield of 80% (calculated based on the amount of organic ligand 9,10-bis(ethynylpyridine)anthracene).
[0031] The unit cell parameters of the new zinc metal organic framework material are 9.6417, 14.2032, 20.4091, 90.0297,
[0032] 89.9718, 106.5940. The novel metal-organic framework material belongs to the triclinic crystal system and the space group P1.

Embodiment 2
[0039] Take 0.009mmol Zn(NO 3 ) 2 ·6H 2 O, 0.005 mmol H 2 bdc, 0.005 mmol 9,10-bis(ethynylpyridine)anthracene, was added to a 4-dram vial, and 1.6 × 10 -2 mol N,N'-dimethylformamide (DMF), and then put the bottle into an oven at 85°C for 48 hours to obtain a crude porous zinc metal-organic framework; wash the crude porous zinc metal-organic framework with ethanol Dry at 80°C to obtain red partial cubic layered crystals—purified porous zinc metal-organic framework materials, with a yield of 15% (calculated based on the amount of organic ligand 9,10-bis(ethynylpyridine)anthracene).
Embodiment 3
[0041] Take 0.009mmol Zn(NO 3 ) 2 ·6H 2 O, 0.090 mmol H 2bdc, 0.090 mmol 9,10-bis(ethynylpyridine)anthracene, was added to a 4-dram vial, and 1.6×10 -2 mol N,N'-dimethylformamide (DMF), and then put the bottle into an oven at 85°C for 48 hours to obtain a crude porous zinc metal-organic framework; wash the crude porous zinc metal-organic framework with ethanol Dry at 80°C to obtain red partial cubic layered crystals—purified porous zinc metal organic framework materials, with a yield of 25% (calculated based on the amount of organic ligand 9,10-bis(ethynylpyridine)anthracene).
