The cover picture shows the crystal structures and colors of meso ‐pentafluorophenyl‐substituted expanded porphyrins. [18]Porphyrin, [26]hexaphyrin, [36]octaphyrin, [44]decaphyrin, [52]dodecaphyrin, [62]tetradecaphyrin, [72]hexadecaphyrin, and [80]octadecaphyrin were synthesized and characterized. As indicated, the absorption bands of these expanded porphyrins are redshifted as their size increases, and [80]octadecaphyrin shows its absorption maximum at 953 nm. Their solutions exhibit various colors, reflecting the macrocyclic conjugation like a rainbow. Details are discussed in the article by A. Osuka et al. on p. 1341 ff.
