Outline of Final Research Achievements |
We herein report following results with the aim of establishing a new method to tune phase transition behaviors of bistable molecules such as spin crossover complexes and electron transfer induced spin state transitions using rotational motions of the molecule in the solid. a) Mononuclear complexes, coordinated by globular ligands such as quinuclidine derivatives directly as solid state rotators, were prepared as the model complexes. Rotational motions in the crystal were studied by means of single crystal X-ray analyses in detail. b) A valence tautomer of cobalt complex coordinated by quinuclidine rotator ligands was prepared. At the room temperature, cobalt ion was determined to be divalent high-spin state and two quinuclidine ligands were rotating. Phase transition properties were now under the investigation.
