Lateral furan‐expansion of polycyclic aromatics, which enables multiple O‐doping and peripheral edge evolution of rylenes, is developed for the first time. Tetrafuranylperylene TPF‐4CN and octafuranylquaterrylene OFQ‐8CN were prepared as model compounds bearing unique fjord edge topology and helical conformations. Compared to TPF‐4CN, the higher congener OFQ‐8CN displays a largely red‐shifted (≈333...
