Influence of chelating ligands on photomagnetic properties of two erbium(III) coordination polymers
The magnetization dynamics of lanthanide coordination compounds are fundamentals governing their potential applications such as information storage or molecular switches. Herein, two two-dimensional coordination polymers [Er(CA)1.5(bpy) (DMF)]n (1) and [Er(CA)1.5(phen) (DMF)]n (2) (H2CA = 2,5-dichloro-3,6-dihydroxy-p-quinone, bpy = 2,2′-bipyridine, phen = 1,10-phenanthroline) were synthesized and fully characterized. By the irradiation of ultraviolet light, 1 and 2 were converted to 1a and 2a which contain light-generated radicals, inducing an increase of χMT at room temperature. A detailed study of the dynamic magnetic property shows that the magnetization dynamics observed for 1 and 1a are dominated by Raman process, but Orbach and Raman processes are observed in 2 and 2a. The structural factors influencing the magnetic properties of this photomagnetic system are discussed.
期刊介绍：
The Journal of Rare Earths reports studies on the 17 rare earth elements. It is a unique English-language learned journal that publishes works on various aspects of basic theory and applied science in the field of rare earths (RE). The journal accepts original high-quality original research papers and review articles with inventive content, and complete experimental data. It represents high academic standards and new progress in the RE field. Due to the advantage of abundant RE resources of China, the research on RE develops very actively, and papers on the latest progress in this field emerge every year. It is not only an important resource in which technicians publish and obtain their latest research results on RE, but also an important way of reflecting the updated progress in RE research field.
The Journal of Rare Earths covers all research and application of RE rare earths including spectroscopy, luminescence and phosphors, rare earth catalysis, magnetism and magnetic materials, advanced rare earth materials, RE chemistry & hydrometallurgy, RE metallography & pyrometallurgy, RE new materials, RE solid state physics & solid state chemistry, rare earth applications, RE analysis & test, RE geology & ore dressing, etc.
