Outline of Final Research Achievements

In this project, we pioneered computational chemistry techniques to clarify the science of transition phenomena in various soft crystals and promoted 17 collaborative research themes with 15 research groups. Major achievements include the development of crystal force field potentials for various organometallic complexes containing metal ions, which could not be treated by molecular force field calculations, enabling crystal structure prediction and dynamics analysis. In addition, the crystal structure prediction using powder X-ray diffraction patterns was made possible, and the characterization of soft crystals whose structure has not yet been determined was made possible. In addition, we established a methodology to predict the mechanical properties of molecular crystals under the application of external forces.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果の学術的意義は、これまで困難であった分子性結晶の結晶構造を推定し、その特性を理論的に予測することを可能にしたことである。特に、第一原理計算で扱うことが困難であった有機金属錯体結晶に対して、古典力学に基づく結晶力場を用いて計算可能にしたことによって、分子動力学シミュレーションや第一原理計算による高精度物性予測へ展開できるようにした。また、分子性結晶の機械特性を計算する手法を確立したことによって、低分子の分子性結晶をナノマシン等の材料や素材としての可能性を広げたことの社会的意義はとても重要であると考えている。
