The Coordination Chemistry And Properties Investigation Of Supramolecular Complexes Based On Nitrogen Herterocyclic Ligands And Carbazole Ligands

The research of MOFs is an active interdisciplinary area, These Metal-OrganicFrameworks have tremendous applications in Luminescence, Catalysis, Adsorption andRecognition. In this thesis, the phototransformation of p-Benzoquinone (Q) in a limited3D Cd(II)–MOF was discussed; a series of carbazole ligands end with pyridine ortriazole and a new1,2,4-triazole bent ligand were synthesized. We synthesized7newcomplexes based on these ligands,and fully characterized them by X-Ray Singel-CrystalDiffraction, IR and Elemental analysis. The Adsorption and Separation properties,Catalytic properties and Luminescent properties by some complexes were alsoinvestigated.I. We achieved the phototransformation of Q in Single-Crystal conditions by usingthe complex [CdL2(ClO4)2]·H2O synthesized by our group. According to the testresults of X-Ray Singel-Crystal Diffraction, EPR, GC-MS, Photoluminescenceand UV-Vis, we explored the transformation conditions and machanismpreliminary.II. A new carbazole ligand L1ends with triazole which is called2,7-di (1-H-1,2,4trizole)-9-butyl-carbazole was synthesized. Complex11was obtained by thecoordination of Cu(II) and L1. We discussed the host-guest properties andcolour responsive adsorption and separation of CH2Cl2, CHCl3of11, Theseparation of aromatics C6-C8was achieved by CH2Cl2CuL12(NO3)2.III. The coordination chemistry by Cd(II) and a carbazole ligand L2ends withtrizole was studied.We obtained three complxes from1D to3D, and found theextention directions of L2and the coordination charactistic of anion influencethe structure of complexes. A cabazole ligand L3ends with pyridine wassynthesized. We obtained27and28by the addition of coligand camphanic acidand Cd(II), Zn(II). The catalytic properties of28was investigated.IV. We obtained a new L4Ligand by the modification of a1,2,4-triazole ligandsynthesized by our group. We got a2D complex29with bigger channel by the coordination of L4and Ag(I). In order to achieve the detection of some organicmolecules,29was used to make the coating of SPME device.The results prove that: the1,2,4-Triazole ligand and carbazole ligand designed byus have excellent coordination properties,and it is important to use these complexes incatalysis, adsorption, separation, and luminescence.
