A Japan-Poland Collaboration for Coupling Molecular Nanomagnetism and Luminescent Thermometry.

This invited Team Profile was created by the Laboratory of Advanced Functional Materials (Tokoro Lab), Division of Materials Science, Faculty of Pure and Applied Sciences, University of Tsukuba (Japan); the Multifunctional Luminescent Materials Group (Szymon Group, MLMG), Faculty of Chemistry, Jagiellonian University, Kraków (Poland); and the Solid State Physical Chemistry Group (Ohkoshi Lab), Department of Chemistry, School of Science, The University of Tokyo (Japan). They recently published an article on a bimetallic cyanido-bridged Tb -Co framework exhibiting a desolvation-induced structural transformation providing high-symmetry trigonal-prismatic [Tb (NC) ] complexes. This induces a strong magnetic anisotropy leading to single-molecule magnet behavior with an energy barrier of 854(26) K, which appears in the cryogenic temperatures range, together with the concomitant luminescent thermometry effect.
