Inorganic zeolite molecular sieve materials are widely used in industry and people's daily life due to their unique functions of adsorption / separation and catalysis. The research team led by Zhang Jian, a researcher at the State Key Laboratory of Structural Chemistry at the Fujian Institute of Material Structure, Chinese Academy of Sciences, was approved by the Ministry of Science and Technology 973 Program, the National Fund Committee Innovation Group Project, the Chinese Academy of Sciences ’Emerging and Cross-cutting Projects, and the Fujian Provincial Outstanding Youth Fund Simulating its unique TO4 tetrahedral framework structure, the designed and synthesized series of metal organic zeolite molecular sieve materials not only have higher specific surface area and excellent pore structure control performance, but also show in the research fields of hydrogen energy storage, carbon dioxide capture and catalysis, etc. Superior performance and potential application prospects. The team used tetrahedral Cu4I4 clusters as the basic building blocks and connected a linear ligand triethylenediamine (dabco) to successfully synthesize a cluster organic framework compound with molecular sieve MTN topology. The structure of the compound contains two types of cage structures, the inner diameter of the cage reaches 2.6nm and 2.0nm respectively, and has a very large pore volume; at the same time, the Cu4I4 cluster is a typical fluorescent light-emitting unit, so the synthesis of the compound is not only a molecular sieve-like The material assembly provides a cluster unit construction mode, and its successful fusion of fluorescence and high pore performance provides new ideas for the development of fluorescent molecular sieve materials. The research work was published in J. Am. Chem. Soc. (2012, 134, 17881-17884). Since the structure of the zeolite molecular sieve is usually a series of TO4 (T = Si4 +, Al3 +, P5 + etc) tetrahedral centers, the tetrahedral coordinated metal center (Zn2 +, Co2 +, Cu +, etc.) is usually used in the design of synthetic zeolite molecular sieve structures. The range of choices is very limited. For example, a high-coordinate metal center can be used to construct a 4-connected zeolite molecular sieve topology, which will effectively broaden the choice of metal centers and further expand the functional applications of such materials. The team used coordination chemistry methods to block the two coordination points of the six-coordinate metal center by using the carboxyl chelation coordination mode, and the remaining four coordination points can form a twisted tetrahedral coordination mode. Along this line of thought, the researchers effectively combined such a six-coordinated but four-linked cobalt acetate center with a tetradentate boron imidazole ligand, and successfully achieved the design of two molecular sieve-like compounds with molecular sieve ACO and ABW topologies, respectively. synthesis. The research work was published in Chem. Eur. J. (2012, 18, 11876-11879). In addition, the research group has also made a series of progress in the gas adsorption and catalytic performance of molecular sieve-like materials. Using the structural design idea of ​​constructing 6-coordination but 4-connection, a chiral porous material with triple interpenetrating diamond topology network was synthesized using 5-carboxybenzimidazole and Ni. At 0 degrees Celsius and 1 atmospheric pressure, the The compound adsorbed CO2 at 94.74 cm3 / g. It is worth mentioning that this compound has a CO2 adsorption capacity of 57.7 cm3 / g at 0 degrees Celsius and 0.1 atmospheres, which is superior to the CO2 adsorption capacity of other chiral porous materials reported so far. The research work was published in ChemSusChem (2012, 5, 1597-1601). The researchers also used the doping method to adjust the performance of molecular sieve materials, replacing the tetrahedral Cu + center part with the Co2 + center in the ZIF-67 structure. The molecular aspect shows more excellent performance. The research work was published in J. Mater. Chem. (2012, DOI: 10.1039 / C2JM35602C). Metal organic zeolite molecular sieve material Wine box, usually refers to the box that holds bottled wine. Materials are: Wooden Box, leather box, metal box and paper box. Different shapes for shock and decoration.

Wine box, also known as red wine box, is usually called wine packaging box or red wine packaging box. As the name implies, it is the outer packaging of wine (red wine), which has the function of protecting red wine for convenient transportation and storage, and at the same time, it is beneficial to wine ( red wine).
1. Wine wooden box (red wine wooden box)
Usually include log wine boxes (multi-purpose materials include pine, paulownia, etc.), imitation mahogany wine boxes (multi-purpose materials include MDF, etc.), and the shapes are diverse and are mostly used for medium and high-end wine packaging.
2. Wine leather box (red wine leather box)
Most of the wine leather boxes (red wine leather boxes) are made of PU, PVC and other artificial leather. The leather packaging is more suitable for the characteristics of wine, and can be divided into single-pack, double-pack, four-pack and six-pack in terms of capacity.
3. Metal wine box (metal wine box)
There are few metal wine boxes in the market and are not widely used. Most of them are made of aluminum alloy, iron, and other alloys.
4. Wine carton (red wine carton)
Wine cartons are mostly made of cardboard, corrugated paper, special paper, etc. Since the raw materials are paper, which is convenient for secondary recycling, the shape can be diversified, and other processes are convenient, so wine cartons are widely used in wine packaging.
