Reaction of the Single Molecule Magnet [Mn12O12(CH3CO2)16(H2O)4] (Mn12) with mesogenic dendritic ligands Li (i = 4, 5) quantitatively yields functional clusters [Mn12O12(Li-H)16(H2O)4] (i = 4, 5) that self-organize into a thermotropic SmA-type liquid crystalline phase. The perturbation of the molecular interface by methylation of the terminal mesogenic cyanobiphenyl groups induces a significant decrease of the clearing temperature without affecting the magnetic properties and the supramolecular organization of the Mn12-based clusters.
