Stimuli‐responsive materials can convert between molecular scale and macroscopic scale phenomena. Two macroscopic static electricity‐responsive phenomena based on nanoscale supramolecular assemblies of a zinc porphyrin derivative are presented. One example involves the movement of supramolecular assemblies in response to static electricity. The assembly of a pyridine (Py) complex of the above‐mentioned derivative in cyclohexane is drawn to a positively charged material, whereas 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 Py‐complexed assembly exhibited a strong movement response towards negatively charged materials. Based on spectroscopic measurements and electron microscope observations, it was revealed that the assembled formation generates the observed response to static electricity.
