Porphyrin derivatives are promising materials that are used for various thin film devices. The molecular aggregation structure of the porphyrin derivatives can be controlled by choosing the combination of the center metal atom and the functional groups attached to the porphyrin ring. In this study, the molecular aggregation structure of tetrapyridylporphyrin (TPyP) thin films is controlled by using the intermolecular coordination bonds between the N atom of the pyridyl group and the metal atom. This method realizes the edge-on orientation of the porphyrin rings, which is a rare arrangement for films of porphyrin derivatives having aryl groups.
