| The photoelectronic functional materials are of novel and important field due to their extensive applications. Functional coordination compounds are basic academic field with potential applications and correlated tightly with the material and informatics sceince. Design and synthesis of coordination polymers becomes a hotspot, which is also a very important and meaningful research direction. Based on the idea, we designed a series of organic ligands with excellent optical properties. At the same time, merit functional coordination complexes were obtained, which have both advantages of organic and inorganic units. Main research efforts were concluded as follow.(1) The recent developments in the research for coordination complexes were reviewed based on a great deal of related literatures. Based on these, new concepts and design of our new metal complexes for the dissertation hatched.(2) Two novel flexible compounds tri(4-imidazolylphenyl)amine (L1), tri(4-pyrazolylphenyl)amine (L2) were successfully synthesized in high yield by Ullmann reaction used with a CuI, 1,10-phenanthroline complexes formed as catalyst, which were fully characterized by elemental analyses, NMR, MS, IR spectra and single X-ray diffraction analysis. Crystal structure analysis showed compounds L1, L2 certain plane, L1 belongs to monoclinic system, P21/c space group, while L2 belongs to orthorhombic system, Pccn space group. In L1, L2, hydrogen bonds exist in adjacent molecular, while in L2, weakπ··πinteractions occur between adjacent layers. The products were characterized by UV-vis spectra, fluorescence and cyclic voltammetry.(3) A series of the novel supramolecular structure complexes were obtained by self-assembling of L1, L2 and metal salts, such as M(SCN)2 and M(NO3)2 through coordinate bonds, hydrogen bonds and interatomic force. Co(L1)2(NO3)2 and Cd2(L1)2(SCN)4 were fully characterized by elemental analyses, IR spectra and single X-ray diffraction analysis. The structure of Co(L1)2(NO3)2 crystallizes in the trigonal space group R(?), and it connects the 34-membered tings through two ligands L1 to generate a 2D framework with cavities (ca. 16.106×10.602(?)). The structure of Cd2(L1)2(SCN)4 crystallizes in the triclinic space group P(?), it generates a 2D framework with cavities (ca. 13.999×13.399(?)). And also the molecules are stacked in pairs through H···S interactions, with an distance of 2.168(?).(4) And the properties of all the compounds have been studied, such as optical properties and TGA. By compared the ligand with complexes in fluorescence, all the complexes emit at almost the same peak position upon excited. Different metal ion has little effect on the fluorescence emission of the complexes. These compounds have a good linear optical properties and good thermal stability, which show that the complexes are potential applicable optical materials.
