Research Abstract

In the case of soft crystals, It is extremely important to develop the technologies for preparing metastable states of soft crystals and elucidate their phase transition phenomena. In this research project, we investigated (1) the application of super-resolution microscopy to soft crystal phenomena, (2) development of the technologies for preparing metastable states of aggregates or oriented thin films before crystallization, (3) molecular modeling-based theoretical calculations of phase transition phenomenon by, and (4) functionalizations of soft crystal phenomena using soft materials. In particular, in (2), we found that the chirality of the thin films prepared by concentrating phthalocyanine solutions depended on the rotational direction of a rotary evaporator. The chiral thin films showed thermochromic and mechanochromic properties, and their transition behaviors from the metastable state to the stable state were clarified.
