Rare earth coordination polymers due to the novel structure and luminescent properties, it has a wide range of applications in the field of catalyst separation extractant, hydrogen storage materials and optical materials. In this thesis, two different carboxylic acid ligands as raw material, and synthesis of a series of rare earth carboxylate coordination polymer micro / nanostructures and their optical properties and adsorption performance and explore its applications. In addition, the formation mechanism of rare earth coordination polymer micro and nano structure, the experimental approach and experimental basis in order to provide for the other rare earth micro / nanostructures synthesis of coordination polymers. Therefore, this study has the theoretical research and practical application value. The main content of the paper is as follows: (1) 4,4 ', 4 \the absence of a catalyst, by simple mixing Solvothermal synthesis of 4,4 ', 4 \micron hollow ball. By elemental analysis, thermogravimetry, X-ray diffraction, infrared, scanning electron microscopy, the products were characterized by means of transmission electron microscopy. The results show The hollow ball amorphous diameter of about 260m-500m. Detailed examination of the impact of factors such as reaction temperature, reaction time, and the actual amount of the solvent composition of Tb-BTB hollow spheres, and to explore the growth mechanism of the of synthetic hollow ball from the inside out. Luminescent properties of Tb-BTB hollow spheres based on the unique luminescent properties of terbium coordination polymers. The results show that the Tb-BTB hollow ball synthetic emits green light in the ultraviolet radiation of a wavelength of 316 nm, with the increase in the amount of Eu3 doped hollow ball to synthesize a product of the emission color from green gradually adjusted to the blue, green, cyan, white, orange, orange-red, and finally turns red, which realized the white light regulation has a certain research value. Also studied the adsorption properties of Tb-BTB hollow spheres, the results show that the adsorption performance of the Tb-BTB hollow ball of methylene blue and rhodamine B such cationic dyes. Further, a similar method was synthesized other REE polymer. The results show that the light rare earth coordination polymer morphology of the smooth surface of the hollow sphere, while the the heavy REE polymer morphology of hollow spheres with sheet coexistence. Earth (2) biphenyl -3,4 ', 5 - tricarboxylic acid synthesis and optical properties of the ligand polymer study based on successfully synthesized Tb-BTB hollow sphere, select another having a similar acid structure with The body for Synthesis of Rare Earth carboxylic coordination polymer. In this section, the use of two simple synthetic method of rare earth biphenyl -3,4 ', 5 - tricarboxylic acid terbium coordination polymers were synthesized. The mixed solvothermal synthesis of flower-like micron structure using TG products were characterized by X-ray diffraction, infrared, and scanning electron microscopy and other means; investigated the solvent composition, reaction temperature, reaction time and other factors of synthetic morphology the impact. In addition, the luminescent properties of the product The results show a strong green light in the visible region. Two ultrasonic synthesis method, the product is a micro-structure of the ellipsoid, to be synthesized by changing the composition of the solvent out of the strip, or filamentous morphology. The other typical rare earth elements such as La, Y, Ce, Eu, etc. coordination polymer, and luminescent properties are discussed.
