The Front Cover shows the more than 100‐year journey of rylene chemistry, from the first synthesis of perylene in 1910 to the very recent report of long rylene ribbons up to dodecarylene. Rylene possesses a unique electronic structure with two interacting cis ‐polyacetylene chains, like the track on a railway. The unique open‐shell diradical character of rylene ribbons and quinoidal rylenes is also highlighted. More information can be found in the Microreview by J. Wu et al.
