The Front Cover shows a photocatalyst depicted as a luminescent jellyfish, which exhibit luminescence on excitation by external stimuli and is analogous to the photocatalyst. The photocatalyst cleaves distinct two carbon‐carbon bonds to form a new carbon‐carbon bond. In their Communication, K. Nakajima et al. describe the development of novel aromatic substitution reactions of cyanoarenes with 4‐alkyl‐1,4‐dihydropyridines by using transition metal polypyridyl complexes as catalysts. In this reaction system, generation of radical cations and anions by single electron transfer processes plays a key role to promote the catalytic reaction. The detailed reaction pathway is investigated by experimental and theoretical methods. More information can be found in the Communication by K. Nakajima et al. on page 1028 in Issue 6, 2016 (DOI: 10.1002/cctc.201600037).
