|Outline of Final Research Achievements
In this research project, we have attempted to synthesize new charged π-electronic systems for fabricating their assemblies and electronic materials and devices and investigating the relations between the properties and assembling modes. In this study, porphyrin Au(III) complexes and deprotonated forms of meso-hydroxyporphyrins were found to act as π-electronic cations and anions, respectively, which form ion pairs in combination with corresponding counterions, resulting in the ordered arrangement and electronic and photophysical properties. The fundamental intermolecular forces between the charged components in the ion-pairing assemblies were examined, driving us to propose iπ-iπ interactions for the stacking of charged π-electronic systems. In addition, other building units of ion pairing assemblies, such as pyrrole-based anion-responsive π-systems and related molecules, were synthesized for electronic properties.
