The pyridyl Imidazolinone metal complexes its diverse structure type and its potential function concern. Order to study and discuss the structure and the nature of the relationship between the imidazolinone pyridyl ligand and its complexes, the solution method and hydrothermal synthesis of the four categories of 12 have not been reported pyridyl imidazolidinone complexes by systematic means of infrared spectroscopy, X-ray single crystal diffraction study of the crystal structure, and complex (1) 5 (9) and (10) thermal gravimetric analysis. Investigated at room temperature, the complexes (1) 4 , (9), (10) and (12) the solid-state fluorescence properties. This paper is divided into the following chapters: Introduction part of the system introduced the concept of the complex, the basic performance, light-emitting principle light and impact factors, as well as the imidazoline ring, pyridyl Complexes research advances. The second chapter describes the structure and performance of a series of complexes of transition metals and ligands Imazapyr synthesis. Direct reaction of the 2 - (4 - isopropyl-4 - methyl-5 - oxo -2 - imidazolin-2 - yl) nicotinic acid and the transition metals copper, manganese, cobalt, zinc, cadmium, and iron salts obtained eight complexes [Cu (Imazapyr) 2 (H 2 O) 2 ] (1), [Mn (Imazapyr) 2 (H 2 O) 2 ] (2), [Co (Imazapyr) 2 (H 2 O) 2 ] (3), [Zn (Imazapyr) 2 (H 2 O) 2 ] (4), [Co (Imazapyr) 3 < / sub>] (5), [Mn (Imazapyr) 2 ] n (6), [Cd (Imazapyr) 2 ] n (7), [Fe (Imazapyr) 2 ] n (8). 4 similar structure for heterogeneity Isomorphously, belongs to the Orthorhombic crystal system, space group Pbca, metal ion coordination environment hexacoordinated octahedral configuration; complexes complexes (1) (5) Rhombohedral crystal system, space group R-3, the coordination environment of the metal ion hexacoordinated octahedral configuration; fit objects (6) 8 similar structure for heterogeneity isomorphous, belongs to Monoclinic crystal system, space group P2 (1) / n, the coordination environment of the metal ion hexacoordinated octahedral configuration. Solid fluorescent properties of the crystal structure was determined by X-ray single crystal diffraction techniques, infrared spectroscopy and complex thermal gravimetric analysis. Complexes (1) 5 complexes belonging to the mononuclear complexes rich hydrogen bonds between molecules through hydrogen bonding to become a one-dimensional chain structure. of the complex was (1) 4, the central ion and two Imazapyr ligand through the form of bidentate chelating ligand and the ligand and two water molecules at the same time, in the complex (5) , the central ion and three Imazapyr ligand by pairs of holding chelated form ligand imazapyr the carboxyl oxygen atoms do not participate in the ligand, the ligand of the ligand as a terminal group ligand. Complexes (6) 8 is a coordination polymer, each Imazapyr ligands as bridging ligands with two different metal ions, ligands, one end is the pyridine ring and the imidazoline ring double The bidentate chelating ligand, and the other end is a monodentate ligand, a metal ion of the carboxyl oxygen atoms in the four different directions with four Imazapyr ligand ligand. The complexes (1) 5 of the thermal gravimetric analysis showed, the part of the complexes have a strong thermal stability, by the fluorescence analysis of the complex was (1) 4 show that complexes have good fluorescence properties. The third chapter describes the crystal structure and properties of four complexes of transition metals and ligands Imazameth synthesis. 2 - (4 - isopropyl-4 - methyl-5 - oxo-2 - imidazolin-2 - yl) -5 - methyl-nicotinic acid and the transition metals cobalt, nickel and copper salts direct reaction to obtain four complex [Co (Imazameth) 3] · 0.5DMF · 4H2O (9), [Ni (Imazameth) 2 (H 2 O) 2 ] · 2C 2 H 6 O 2 (10), {[Cu 2 (Imazapyr) 2 (4,4 '-bpy) 2 ] · (CH 3 OH) (H 2 O) (ClO 4 )} n (11), {[Ni 2 (Imazapyr) 2 (4,4 '-bpy) ] · (CH3OH) (H2O) (ClO4)} n (12). Complexes (9) is Trigonal crystal system, space group R-3, the coordination environment of the metal ion hexacoordinated octahedral geometry; complexes (10) Orthorhombic crystal system, space group Pbcn metal ion coordination environment of hexacoordinated octahedral configuration; complexes (11), (12) similar to the structure belongs to Monoclinic crystal system for heterogeneity Isomorphously, space group P2 (1) / n, metal ion coordination environment for the five-coordinate pyramid configuration. Solid fluorescent properties of the crystal structure was determined by X-ray single crystal diffraction techniques, infrared spectroscopy and complex thermal gravimetric analysis. Complex (9) and (10) as belonging to the mononuclear complexes, complexes (9), the central ion and three ligand molecule through the bidentate chelate ligand in the form of the carboxyl group oxygen atom Imazameth not involved in ligand. The complexes have a large number of crystal water molecules, and these water molecules by hydrogen bonds to form a cube water clusters, each of the water cluster molecule with six ligand molecule connected, rich in hydrogen bonding interactions in the complexes, complexes final is connected to become a flat mesh structure in the complex (10), the central ion and two Imazameth ligand through the bidentate chelating ligand in the form of central ion ligand and two water molecules, Imazameth the carboxyl oxygen atoms are not involved in the ligand, the ligand of the ligand as a terminal group the ligand. Complexes (11) and (12) is a coordination polymer, each one Imazameth ligand as bridging ligands with two different metal ions, ligands, one end is the pyridine ring and the imidazoline ring bidentate chelating ligand bit, the other end of the carboxyl oxygen atoms of monodentate ligand Imazameth ligand metal ion to become a one-dimensional chain structure, 4,4 '- bipyridine as bridging ligand and metal ion coordination, 4,4 '- bipyridine the Imazameth ligand connected one-dimensional chain structure connected to a two-dimensional network structure. Meanwhile, complexes rich in hydrogen bonding, by hydrogen bonds, complexes eventually be connected into a three-dimensional supramolecular structure. Complexes (9) and (10), thermal gravimetric analysis showed that the complexes have poor thermal stability, by the complex (9), (10) and (12) of the fluorescence analysis showed that the complexes have good fluorescence properties. Chapter IV summarizes the achievements and shortcomings of this thesis, the requirements and expectations of future work.
