resumo
Sensors are increasingly present in the everyday life in widespread technological applications, and engineering smart systems able to simultaneously detect different physical quantities represents a scientific challenge. Taking advantage of the molecular chemistry realm that offers the possibility to finely adjust physical properties, it is demonstrated herein that the luminescent single-molecule magnet [Dy(acac)(3)(H2O)(2)]center dot H2O (acac = acetylacetonate) acts as a dual and synchronous thermometric/magnetic optical sensor in large ranges (10.0-180.0 K and up to approximate to 45 T) holding the promise to detect their variations in future devices.
