Octahedral anionic rhenium clusters are obtained by high-temperature solid-state chemistry synthesis as single crystals or powders within which their charge is counter balanced alkali cations. The ceramic-like behavior of the Re6 based inorganic compound limits strongly use in functional devices. We present herein a facile route to introduce these self-organized hybrid organic–inorganic material. By replacing countercations mesogenic organic ones, polarized optical microscopy (POM), DSC, X-ray, magnetic, fluorescence, and cyclic voltammetry techniques confirm that lyotropic thermotropic liquid crystal material, able switch reversibly from bright red NIR luminescent form magnetic green-colored one, obtained.
