Abstract
Metal-organic framework material [Cd(tib)(dnbpdc) (H2O)]·2DMF·2H2O (1) [tib = 1, 3, 5-tris(1-imidazolyl)benzene, H2dnbpdc = 2, 2′-dinitro-4, 4′-biphenyldicarboxylic acid] was synthesized and characterized by Thermogravimetric analyses (TGA), Powder X-ray diffraction (PXRD) analyses and Bruker D8 Advance X-ray diffractometer. The results showed that 1 was a 1D chain structure to be joined together by hydrogen bonds to generate a 3D supramolecular structure. CO2 and N2 adsorption behavior of the material was studied. It is significative that 1 can selective sorption of CO2.
Highlights
In the past decades, remarkable attention have been concentrated on the design and synthesis of functional metal-organic frameworks (MOFs) materials due to their rich and varied structures as well as potential application, such as gas storage and separation, magnetism, heterogeneous catalysis, photoluminescence and so on. [1,2,3,4,5,6,7,8,9,10]

Summary
Remarkable attention have been concentrated on the design and synthesis of functional metal-organic frameworks (MOFs) materials due to their rich and varied structures as well as potential application, such as gas storage and separation, magnetism,, heterogeneous catalysis, photoluminescence and so on. [1,2,3,4,5,6,7,8,9,10]. It is still a challenge to investigate factors influencing the structural building of MOFs because varied factors can affect the structure and property of MOFs [11, 12] Such factors mainly include the selection of organic linkers, metal ions, reaction temperature. A rigid tridentate ligand 1,3,5-tris(1-imidazolyl)benzene (tib) with specific structure and interesting properties has been used in construction of MOFs [15,16,17,18,19,20]. It is meaningfull with imidazole-containing ligand tib and dicarboxylic acid H2dnbpdc to construct MOFs with novel structures and properties. It is interesting that 1 shows selective and hysteretic sorption of CO2 over N2
