在溶剂热条件下成功合成了基于异位配体的微孔MOF,并使用单晶和粉末X射线衍射,TGA,FTIR和微量分析对其进行了全面表征。X射线单晶衍射分析表明,标题MOF包含丰富的无机硝酸根离子,修饰了通道表面,可作为C 2 H 2识别位点。通过单组分平衡吸附测量和IAST计算评估了其在CO 2和CH 4上对C 2 H 2的选择性气体吸附性能,确定了其在C 2 H 2方面的潜力分离纯化。在环境条件下,C 2 H 2的吸收容量达到92.2 cm 3(STP)g –1,而IAST预测的等摩尔C 2 H 2 -CH 4和C 2 H 2的吸附选择性分别高达30.6和4.5。-CO 2二元混合气。此外,DFT计算研究表明,无机硝酸根离子在优先吸附C 2 H 2而不是CO 2和CH 4方面起着非常重要的作用。

The present invention is directed to compounds that are inhibitors of cysteine protease, in particular, cathepsins B, K, L, F, and S and are therefore useful in treating diseases mediated by these proteases. The present invention is directed to pharmaceutical compositions comprising these compounds and processes for preparing them.
Supramolecular self‐assembly of 24 forklike mesogenic ligands and 12 transitionmetalions led to the formation of giant spherical coordinationcomplexes that exhibit liquid‐crystalline (LC) phases. Self‐healing LC supramolecular gels were also obtained through the introduction of these LC nanostructured supramolecular giant spherical complexes into dynamic covalent networks formed by cross‐linkers

Crystallographic and topological analyses identify that both complexes have new framework topologies. Complex 1 is a (3,8)-connected 2-nodal 3D net with a point (Schlafli) symbol of (42.5)2(44.510.67.76.8), while 2 is a (4,5)-connected binodal net with a point (Schlafli) symbol of (42.63.8)(42.65.83). Furthermore, magnetic investigation shows that both complexes exhibit overall weak antiferromagnetic coupling between

Recently, metal–organic frameworks (MOFs) have been investigated as potential materials for CO2capture and light hydrocarbonstorage/separation due to their high porosity, large surface area, and tunable skeleton structures. In this work, the six cobalt-based MOFs 1–6 were successfully synthesized under solvothermal conditions by a mixed-ligand strategy. 1 and 2 have the same framework structure with a topology

6 present rarely observed chiral anh (flu-3) networks with left-handed double helical chains. The structural investigation indicates that the steric tuning of linkers may essentially dictate the resulting diverse MOF structures. Furthermore, the MOFs presented here can be regarded as an ideal structural platform for a better understanding of the assembly of (3,6)-connected rtl, ant, and chiral anh
