Outline of Final Research Achievements

In this work, we tried to investigate multi-step vapochromism, to explore possibility for quantitative analysis of vapor molecules. To achieve the multi-step vapochromism, we focused on halogen atom modification in metal complexes because halogen atoms have been known to interact with other atoms through various forms of interactions.
As the result, we found metal complex with halogenated ligand exhibited vapochromism and halogen atoms formed various interaction modes in their crystal structure. Moreover, we also found another metal complex exhibit polymorphism which forms different crystal structure with same molecular composition, maybe due to the halogen atom modification.

Academic Significance and Societal Importance of the Research Achievements

本研究では、ハロゲン修飾がベイポクロミズムを含む外部刺激応答性物質の創製や、応答の多段階化にとって有望である可能性を見出した。外部刺激応答性物質は分子設計の時点でその有無を予想することは難しいが、ハロゲン修飾によってこれを付与できる可能性がある。この知見は、外部刺激応答性物質の研究を推進するための一助となり得る。
