電荷双安定性に由来する擬一次元ハロゲン架橋金属錯体の動的挙動創出と可視化

Metal complexes have originally many kinds of bistability owing to charge, spin, lattice etc. Recently, there has been much effort for controlling the macroscopic properties by the molecular bistability through cooperative phenomena. In the one-dimensional systems, especially, dynamics can be expected owing to the bistability of molecules because cooperativity is not so strong comparing to three-dimensional systems. We have studied on the charge dynamics in quasi-one-dimensional halogen-bridged metal complexes by using charge bistability of metal ions. In this review, a method for creating the charge bistability by reducing band gap energy and new method for detecting such a charge bistability by using scanning tunneling microscopy (STM) has been reported.
