Since the creation of coordination chemistry by the young scholars Werner A at the end of the nineteenth century and the beginning of the twentieth century, organic metal complex hybrid as the object of studies, the combination of the traditional chemistry, physics, life science, materials science and environmental science has become the combining points of many disciplines. The diverse structure and the novel physical, chemical and biological functions of metal–supramolecular coordination polymers are so remarkable that it has been used in optoelectronics, nonlinear optics, ultra-molecular membrane, catalysis, nanotechnology and bio-medical fields. Terpyridine and its derivatives not only have a unique structure, which can be combined with a variety of transition metal chelate to form a stable complex, but have excellent optical, electrical, magnetic, and catalytic elements and other characters such as catalysis, therefore various triple pyridine derivatives and their metal coordination polymers have been widely used in supra-molecular chemistry.This thesis focuses on the synthesis of the series of rigid terpyridines and their corresponding series of ZnII,CuII,NiII,MnII complexes of terpyridine were prepared. All the synthesized compounds were characterized by NMR and IR spectroscopy along with element analysis. Two new crystal structures were determined by X-ray diffraction. The thesis is divided into three chapters:The first chapter introduces the research background of this thesis, generally presenting the synthetic methods of the terpyridines, the research development of their metal complexes and their current situation in supra-molecular chemistry. The thesis also discusses the significance of topics.The second chapter introduces four terpyridines synthesized by using the grinding solid-synthetical method improved by Kr?hnke:4'-pheny-2, 2 ': 6', 2''-terpyridine (L1), 1, 3-bis(2, 2 ': 6', 2''-terpyridine) benzene (L2), 1, 4-bis(2, 2 ': 6', 2''-terpyridine) benzene ( L3), 1, 3, 5–tris(2, 2 ': 6', 2''-terpyridine) benzene (L4), and from these terpyridine ligands, a series of ZnII,CuII,NiII,MnII metal acetate complexes were synthesized: Zn(L1)(OAc)2,Zn(L1)2(OAc)2,Zn2(L2)(OAc)4,Zn2(L3)(OAc)4,Zn3(L4)(OAc)6,Cu(L1)(OAc)2,Cu(L1)2(OAc)2,Cu2(L2)(OAc)4,Cu2(L3)(OAc)4,Cu3(L4)(OAc)6,Ni(L1)(OAc)2,Ni(L1)2(OAc)2,Ni2(L2)(OAc)4,Ni2(L3)(OAc)4,Ni3(L4)(OAc)6,Mn(L1)(OAc)2,Mn(L1)2(OAc)2,Mn2(L2)(OAc)4,Mn2(L3)(OAc)4,Mn3(L4)(OAc)6,The third chapter is devoted to the characterizations of the synthesized compounds by the use of NMR, and X-ray diffraction and the discussion.
