Synthesis and characterization of two self-assembled [Cu₆Gd₃] and [Cu₅Dy₂] complexes exhibiting the magnetocaloric effect, slow relaxation of magnetization, and anticancer activity

Abstract

Two new paths for coordination driven self-assembly reactions under the binding supports of 2-((1-hydroxy-2-methylpropan-2-ylimino)methyl)-6-methoxyphenol (H2L) have been discovered from reactions of Cu(ClO4)2·6H2O, NEt3 and GdCl3/DyCl3·6H2O in MeOH/CHCl3 (2:1) medium. Similar...

Homochiral Cu6Dy3 single-molecule magnets displaying proton conduction and a strong magneto-optical Faraday effect

“…Furthermore, they are also involved in the construction of many 3d-4f SMMs. 29 Among them, Dy-Cu SMMs can exhibit good magnetic relaxation properties without applying an external dc field, [30][31][32][33][34][35][36][37] but most of such SMMs reported in the literature are non-chiral. On the other hand, chiral SMMs with triangular Dy 3 structural units are particularly interesting because they can exhibit spin chirality as single-molecule toroics.…”
