| Outline of Final Research Achievements |
In this study, we aimed to establish a novel supramnolecular fluorescent solid system, which is constructed through self organization of multi components such as functional molecules and structural modulation molecules that involve only ubiquitous elements. Furthermore, structure-property relationship was expected to be revealed via a series of molecular arrangements tuned systematically.
We constructed supramolecular assemblies of polycyclic aromatic hydrocarbons with amino or sulfonic acid moieties and various mineral acid or amines, and investigated their emission properties. As a result, we achieved various molecular arrangements that slightly differ each other, enabling to discuss detailed structure-property relationship. Based on this, we proposed new hypothesis regarding molecular stacking way to provide excimer emission. Moreover, drastic fluorescence color change was achieved upon adsorption and desorption of guest molecules into/from the supramolecular solid systems.
