Description
For two decades, anisotropic lanthanide(III) complexes stay at the forefront of research devoted to molecular objects called single-molecule magnets (SMMs), showing magnetic memory effect at the single-ion scale.[1] Nevertheless, the main issue to address for SMMs lies in the temperature working range, with the record held by an organometallic Dy(III) complex, operating up to 80 K.[2] As it is well established, to implement SMMs into novel devices some competitive factors have to be met,[3] we and others focused on luminescence originating from Ln(III) f-f electronic transitions, hard to achieve for classical ferromagnets. We discovered, that the optical signal in the vis or NIR emission ranges can be employed to follow the temperature of Ln(III)-based SMMs, parameter which is crucial in terms of the magnetic memory effect.[4] Here, the different strategies to achieve optical thermometers and their advantages will be presented.
