The Front Cover shows three types of cationic pyridinium‐substituted chlorophyll‐ a derivatives with different π‐conjugated cyclic tetrapyrroles (bacteriochlorin, chlorin, and porphyrin). Their photoinduced intramolecular electron transfer from the tetrapyrrole to the pyridinium group depended on their π‐conjugation degrees. The cover image was inspired by a Japanese traditional children's song “Usagi”, which talks about jumping rabbits which are looking at the full moon. People believed in the mystic powers of the moonlight and scientists pursue moonshots. Rabbits with silver grasses in front of the moon is one of the typical autumn images in Japan.
