Outline of Final Research Achievements |
Toward achieving room-temperature molecular magnets, we developed a novel multiradical and multichelating ligand, which has a chelating ability on multiple radical functional groups, and its polynuclear complexes. (1) One-dimensional metal complexes were successfully obtained by complexing the radical ligand with copper(II) chloride and bromide. The complexes showed extremely strong metal-radical magnetic couplings (~1000 K) beyond a thermal energy of room temperature, which were clarified by means of magnetic measurements and quantum chemical calculations. (2) Dinuclear lanthanide(III)-radical complexes were synthesized, where we demonstrated a coordination ability to lanthanide ions on the two radical moieties in the multiradical lingad.
