Two new coordination polymers,[Co(BIPA)(bpp)](1) and [Zn(BIPA)(bpp)(H2O)](2)(H2BIPA = 5-bromoisophthalic acid,bpp = 1,3-di(4-pyridyl)propane) have been synthesized via hydrothermal reactions.The two ... Two new coordination polymers,[Co(BIPA)(bpp)](1) and [Zn(BIPA)(bpp)(H2O)](2)(H2BIPA = 5-bromoisophthalic acid,bpp = 1,3-di(4-pyridyl)propane) have been synthesized via hydrothermal reactions.The two compounds were characterized by elemental analysis,IR spectra,TG analysis and single-crystal X-ray determination.Compound 1 crystallizes in triclinic,space group P1 with a = 9.0316(13),b = 10.1179(14),c = 11.8884(17) ,α = 68.022(2),β = 84.749(2),γ = 77.791(2)°,V = 984.5(2) 3,Z = 2,C21H17BrN2O4Co,Mr = 500.21,Dc = 1.687 g.cm-3,μ = 2.932 mm-1,S = 0.981,F(000) = 502,R = 0.0440 and wR = 0.1357 for 3773 observed reflections with I 2σ(I).Compound 2 crystallizes in the monoclinic system,space group P21/c with a = 7.8466(10),b = 27.483(4),c = 9.6583(13) ,β = 96.663(3)°,V = 2068.8(5) 3,Z = 4,C21H19BrN2O5Zn,Mr = 524.66,Dc = 1.685 g.cm-3,μ = 3.155 mm-1,S = 0.969,F(000) = 1056,R = 0.0441 and wR = 0.0517 for 4058 observed reflections with I 2σ(I).The two compounds are constructed from the BIPA2-and bpp ligands but they exhibit different kinds of one-dimensional chain structures.In 1,the chains are composed of the Co(Ⅱ) ions and BIPA2-ligands,and the chains are further extended into a 2D framework structure by π...π interactions of the benzene rings from the BIPA2-ligands between the adjacent chains.In 2,the chains are made up of Zn(Ⅱ) ions and BIPA2-ligands through another fashion,and the chains are further linked via hydrogen bonding interactions to yield a two-dimensional supramolecular layer structure.Furthermore,the bpp ligand features two kinds of different coordination modes in the two compounds. 展开更多

Over the past few decades, coordination polymers/metal organic frameworks (CPs/MOFs) have drawn a great deal of attention for diverse applications due to their advantages of intrinsically ttLnable chemical structure, flexible architecture, high pore volume, high surface area, multifunctional properties, etc. To date, numerous CPs/MOFs have been developed and employed for the treatment and control of gaseous pollutants, such as volatile organic compounds (VOCs), through capture, sorptive removal, and catalytic degradation. Nevertheless, there are also some key drawbacks and challenges for the practical application of these systems (e.g., poor selectivity, high energy (and fiscal) cost, high synthesis cost, low capacity, and difficulties in regeneration and recycling). In this review, recent developments in CPs/MOFs research are described with their associated mechanisms for capture, sorptive removal, and catalytic degradation of VOCs. To this end, we discuss the key variables and challenges for afforded abatement of VOCs through CPs/MOFs technologies. Hopefully, this review will help the scientific community set future directions for the advancement of CPs/MOFs techniques for the effective management of diverse environmental issues. 展开更多
