Outline of Final Research Achievements

Stimuli-responsive materials can convert between molecular scale and macroscopic scale phenomena. We present two macroscopic static electricity responsive phenomena based on nanoscale supramolecular assemblies of a zinc porphyrin derivative. One example involves the movement of supramolecular assemblies in response to static electricity. The assembly of a pyridine complex of the above derivative in cyclohexane is drawn to a positively charged material, while the assembly of a 3,5-dimethylpyridine complex is drawn to a negatively charged material. The second phenomenon involves the movement of a non-polar solvent in response to static electrical stimulation. A cyclohexane solution containing a small quantity of the pyridine-Zn porphyrin complex exhibits a strong movement response towards negatively charged materials. Based on spectroscopic measurements and electron microscope observations, we reveal that the assembled formation generates the observed response to static electricity.
