| Coordination Polymers are metal ions or metal clusters as nodes,through the organic ligands containing nitrogen and oxygen as overseas linkage,through the interaction between molecules or hydrogen bonds to build a one-dimensional,two-dimensional or three-dimensional structure.Thirteen novel coordination polymeres were synthesized by pyridazine carboxyl derivatives,diimidazole and V-type dicarboxyl ligands with transition metal ions Cu2+,Ni2+,Co2+,Zn2+and Cd2+.Cu(PDC)2·H2O(SNUT-1),{[Cu(1,3-BIP)(PDC)(NO3)]·2H2O}n(SNUT-2),{[Co(PDCA)2]·H2O}n(SNUT-3),[Zn(PDCA)]n(SNUT-4),{[Ni(H2O)2(1,3-BIP)2]·1,4-BDF}n(SNUT-5),[Zn(1,3-BIP)(1,4-BDF)]n(SNUT-6),[Cd(1,3-BIP)(1,4-BDF)1.5(H2O)]n(SNUT-7),[Co(1,3-BIP)(1,3-BDC)]n(SNUT-8),{[Co(BCT)(1,3-BIP)(H2O)3]n.DMF}n(SNUT-9),{[Co2(BCT)(1,3-BIP)2(H2O)]n·DMF}n(SNUT-10),{[Ni(BCT)(1,3-BIP)(H2O)3].DMF}n(SNUT-11),{[Zn(1,3-BIP)(BCT)]·DMF}n(SNUT-12),{[Zn2(BMIP)2(BC T)2/3]·DMF}n(SNUT-13).Meanwhile,the structural characterization of these coordin-ation polymeres is detailed.This paper includes five chapters.In the first chapter,the basic concepts of coordination polymeres are summarized,and the wide application of coordination polymeres in fluorescence sensing,degradation of organic dyes and gas adsorption is introduced.Finally,the basis of topic selection,significance and research progress of this paper are simply explained.In the second chapter,a coordination polymer Cu(PDC)2·H2O(SNUT-1)was constructed by HPDC and Cu,and{[Cu(1,3-Bip)(PDC)(NO3)]·2H2O}n(SNUT-2)was obtained by mixing HPDC with 1,3-Bi P ligand.{[Co(PDCA)2]·H2O}n(SNUT-3)and[Zn(PDCA)]n(SNUT-4)were synthesized by the coordination of dicarboxylic ligand PDCA with metal Co and Zn,respectively.The coordination polymer 1-4 was characterized by infrared,powder X-ray diffraction and thermogravimetry.Meanwhile,the antibacterial performance and density functional(DFT)calculation of the coordination polymer were also studied.The uv diffuse reflection of the coordination polymer SNUT-2-4 was carried out,the photocatalytic degradation performance of the coordination polymer 2-4 was studied.In addition,the surface of the coordination polymer SNUT-1 was analyzed.In chapter 3,1,3-BIP,1,4-BDF were used to synthesize three novel coordination polymeres with Ni,Zn and Cd,respectively.{[Ni(H2O)2(1,3-BIP)2]·1,4-BDF}n(SNUT-5),[Zn(1,3-BIP)(1,4-BDF)]n(SNUT-6),[Cd(13-BIP)(1,4-BDF)1.5(H2O)]n(SNUT-7).The coordination polymer SNUT-5-7 was characterized by infrared,powder X-ray diffraction and thermogravimetry,and the solid-ultraviolet diffuse reflection and photocatalytic degradation properties of coordination polymer 6 were studiedIn chapter 4,six novel coordination polymeres[Co(1,3-BIP)(1,3-BDC)]n(SNUT-8)were constructed with Co,Ni and Zn,respectively,using organic ligands 1,3-BIP,1,3-BDC and H2BCT.{[Co(BCT)(1,3-BIP)(H2O)3]n·DMF}n(SNUT-9),{[Co2(BCT)(1,3-BIP)2(H2O)]n·DMF}n(SNUT-10).{[Ni(BCT)(1,3-BIP)(H2O)3]·DMF}n(SNUT-11),{[Zn(1,3-BIP)(BCT)]·DMF}n(SNUT-12),{[Zn2(BMIP)2(BCT)2/3]·DMF}n(SNUT-13).Coor-dination polymer SNUT-8-13 was characterized by infrared,powder X-ray diffraction and thermogravimetry,solid-ultraviolet diffuse reflection of coordination polymer SNUT-8-13,followed by surface analysis of coordination polymer SNUT-8,10 and 11,and finally,the photocatalytic degradation properties of coordination polymer SNUT-9,12and 13 were studied.Chapter 5 Results and prospects. |
