Magnetic interplay between two different lanthanides in a tris-phthalocyaninato complex: a viable synthetic route and detailed investigation in the bulk and on the surface

摘要: Future applications of molecular units in quantum information technologies require a fine control at the single molecule level. This includes choice each functional element, intramolecular interaction and robustness molecules when dispersed on substrate. Keeping these goals mind, we designed synthesized heterometallic phthalocyaninato-complex including two different lanthanides moiety, namely [PcDyPcTbPc*] (Pc being phthalocyanines; Pc* 2,3,9,10,16,17,23,24-octahexyl-substituted phthalocyanines). Full magnetic characterization was performed down to mK temperature range bulk microcrystals by means AC susceptibility, DC magnetization (including microSQUID) specific heat measurements. A weak, yet sizeable, between is clearly detected techniques, altering behavior lanthanide as observed parent [LnPc2] complexes. Isolated HOPG Au surface liquid phase deposition are proven maintain their main chemical features combined XPS, XAS XMCD analysis lie with one Pc ligand flat surface. Opening small but sizable hysteresis loop 1.8 K directly both Tb Dy sites proving retention
