Embodiment 1

[0052] {(Him)[Sm(ip) 2 (H 2 O)]} n Synthesis

[0053] Sm(NO 3 ) 3 ·6H 2 O (0.5mmol, 231mg), isophthalic acid (0.5mmol, 83mg), and imidazole (1mmol, 68mg) were dissolved in 20ml of distilled water, stirred evenly, and the pH value of the reaction system was adjusted to 8-9 with sodium hydroxide solution, Then add it into the reaction kettle, heat up, and react at 150°C for 120 hours, gradually lower the temperature, cool to room temperature, filter, wash with water, and dry to obtain blocky yellow crystals. The resulting crystals were monochromated with graphite molybdenum target MoKα rays on the Rigaku RAXIS-RAPID single crystal X-ray diffractometer of Japan Rigaku Corporation. Diffraction data were collected at 293(2)K in ω-scan mode. The initial structure of the crystal was solved by the direct method using the SHELX-97 program, and then the coordinates of all non-hydrogen atoms were obtained by the difference Fourier synthesis method and the least square method, and...

[0057] {(Him)[Eu(ip) 2 (H 2 O)]} n Synthesis

[0058] Will Eu 2 o 3 (0.25mmol, 88mg), isophthalic acid (3.75mmol, 623mg), and imidazole (3.75mmol, 255mg) were dissolved in 30ml of distilled water and 20ml of methanol, stirred evenly, and the pH value of the reaction system was adjusted with sulfuric acid solution=5~6 , and then added to the reaction kettle, heated up, reacted at 130 ° C for 240 hours, gradually lowered the temperature, cooled to room temperature, filtered, washed with water, dried to obtain block light yellow crystals. The resulting crystals were monochromated with graphite molybdenum target MoKα rays on the Rigaku RAXIS-RAPID single crystal X-ray diffractometer of Japan Rigaku Corporation. Diffraction data were collected at 293(2)K in ω-scan mode. The initial structure of the crystal was solved by the direct method using the SHELX-97 program, and then the coordinates of all non-hydrogen atoms were obtained by the difference Fourier synthesis method and...

[0063] GdCl 3 '6H 2 O (0.5mmol, 186mg), isophthalic acid (1.0mmol, 166mg), and imidazole (0.5mmol, 34mg) were dissolved in 9ml of distilled water and 6ml of ethanol, stirred evenly, and the pH value of the reaction system was adjusted with triethylamine=9 ~10, then added to the reaction kettle, heated up, and reacted at 80°C for 10 hours, then gradually lowered the temperature, cooled to room temperature, filtered, washed with water, and dried to obtain massive light green crystals. The resulting crystals were monochromated with graphite molybdenum target MoKα rays on the Rigaku RAXIS-RAPID single crystal X-ray diffractometer of Japan Rigaku Corporation. Diffraction data were collected at 293(2)K in ω-scan mode.

Description

technical field [0001] The present invention relates to rare earth complex materials, in particular to rare earth organic coordination polymers with imidazolium cations as templates, in particular to rare earth organic coordination polymers with imidazolium cations as templates and isophthalic acid dianions as ligands and its preparation method. The prepared rare-earth organic coordination polymer has good application prospects in the fields of luminescence, catalysis, adsorption, magnetism, ion exchange, polymer material additives and the like. Background technique [0002] Coordination polymers refer to inorganic-organic hybrid materials in which metals or metal clusters and organic ligands are interconnected, also known as metal-organic framework materials. [0003] In recent years, the design and synthesis of coordination polymers have aroused great interest. This is not only because such materials have pores, large specific surface area, special host-guest relationshi...
