Research Outline

In this project, aiming for the rational construction of two-dimensional (2D) crystals with structural flexibility, that is, “2D soft crystals”, we challenge to explore the methods to develop dynamic functions in crystalline 2D lattices. To realize 2D soft crystals, a rotatable unit “ferrocene” is used. In the past researches, it is worth noting that the fact that “rotational behavior is not directly used for dynamic function of crystal”. The reason is simple. Even if we design and synthesize molecules showing rotational motions in solution, once molecules are crystallized, the molecules tightly pack each other, thereby interfering with each other’s flexible motions. Completely different approaches are required to realize the dynamic behavior in the crystalline state. The principal investigator has contributed to the development of various stimuli-responsive porous crystals. From the experiences, the idea “it is possible to reasonably synthesize 2D soft crystals by introducing cooperative movement as a simple geometric requirement, forced to move in conjunction with each other” was conceived.
