A new ionic liquid with sugar-based ligand has been prepared andused to coordinate cobalt(II), at low loading, in an ionic liquid solution.The system obtained reveals magnetic switching and markedthermochromism in solution/polymer films over a convenienttemperature range (20–60 °C). This system is self-contained,devoid of any volatile substances, and reproducible over multiplethermal cycles. The colour change can be attributed to a change inthe coordination geometry from octahedral (pink) at room temperatureto tetrahedral (blue) on warming, monitored by 59Co NMRspectroscopy, which was used for the first time to study thechange. This material may find applications in stimuli-responsivesmart systems aimed at energy storage applications.
